The Best Free D&D Campaigns & One-Shots (2026)
The lists you find when you search for D&D free campaigns have a habit of linking to adventures that stopped being free years ago. The most famous casualty is Lost Mine of Phandelver, recommended in a thousand roundups and quietly removed from D&D Beyond's free offerings when its expanded paid version arrived. Click one dead link and you stop trusting the other nine.
So every entry below is genuinely free and was personally checked at the time of writing, with a link to the official source. Nine adventures, five genres, and honest prep warnings for each, because free means the adventure costs nothing, and it says nothing about how much work the DM has left to do.
If a link below has changed since publication, tell us and we will fix it the same week.
The Quick-Pick Table (D&D Free Campaigns at a Glance)
| Name | Length | Levels | Best for |
|---|---|---|---|
| Death House | One-shot (1-2 sessions) | 1-3 | Gothic horror, Halloween tables |
| Frozen Sick | Short campaign | 1-3 | Mystery lovers, Wildemount fans |
| Peril in Pinebrook | One-shot | New players | First games, young players |
| Prisoner 13 | One-shot | 4 | Heist night with real stakes |
| A Most Potent Brew | One-shot | 1 | A first dungeon for everyone |
| A Wild Sheep Chase | One-shot | 4-5 | Comedy, mid-level parties |
| The Wolves of Welton | One-shot | 2-3 | Gentle investigation, new DMs |

| Tomb of the Serpent Kings | Short campaign | Low (OSR) | Old-school dungeon crawling |
A note on what you will not find here: a genuinely free, full-length campaign, because since Phandelver left the free list, none of the current official offerings runs past the early levels. The two short campaigns below are the closest honest substitutes, and both can grow into something longer with a little gardening.
Death House (Wizards of the Coast)
The free introduction to Curse of Strahd, and still the best two sessions of gothic horror money can decline to buy. A haunted townhouse in Barovia, two children on the doorstep, and a descent that gets worse the politer it seems. It takes characters from levels 1 to 3 and works beautifully as a standalone haunted-house story with the vampire lord left entirely offstage.
The first time I ran it, our wizard Fenwick hid inside a wardrobe from the animated armour on the upper landing, rolled a one on his escape, and spent the fight being walked downstairs inside the wardrobe. My table still refers to hiding as 'doing a Fenwick'. The house earns that kind of memory.
Honest prep warning two things. The basement finale punches well above a 2nd-level party's weight, so read it carefully and be ready to soften it for small groups. And the backstory involves the deaths of children, which deserves a quiet check with your table before game night rather than a surprise during it.

Frozen Sick (Wizards of the Coast, free on D&D Beyond)
A short campaign, levels 1 to 3, and the best free mystery in the official catalogue. A creeping disease is killing people in a small town on Critical Role's continent of Wildemount, and the party follows the infection backwards to its source across ice fields and ruins. The structure is a proper investigation with clues, suspects and travel, and it teaches a table how to play detective without a murder board.
Nothing about it actually requires Wildemount. Rename the towns and it drops into any cold corner of your own setting in about ten minutes.
Honest prep warning the middle third can sag if the clue trail goes cold, so keep a list of three portable clues ready to surface wherever the party actually looks. And track the disease rules on paper; they involve enough moving parts that you should never trust your memory mid-session.

Peril in Pinebrook (Wizards of the Coast)
A free PDF built as a genuine tutorial: the party finds a newborn dragon and must carry it home to a mother whose lair is under attack. It explains the game as it goes, telling a brand-new DM when to call for a Perception check and why, which no other official adventure bothers to do. If you are introducing children, a partner or complete newcomers to the game, this is the kindest on-ramp Wizards has ever published.
Honest prep warning experienced tables will finish it quickly and find the combat soft, because it was never written for them. Run it for the audience it was made for and it shines; run it for your veteran Thursday group and expect gentle heckling.

Prisoner 13 (Wizards of the Coast, free on D&D Beyond)
A complete heist for 4th-level characters, lifted from Keys from the Golden Vault and given away free. The party breaks into Revel's End, a panopticon prison in a frozen waste, to extract information from a crime boss who has no intention of making it easy. There is a proper suspicion mechanic, multiple routes in, and detailed security that rewards planning, which makes it the rare free adventure with genuine teeth.
Honest prep warning read the guard schedules and security layout twice, because improvising a panopticon under pressure is miserable. And decide in advance what happens when the party goes loud, since heists collapse into sieges the moment someone rolls a natural one on a stealth check, and they will.

A Most Potent Brew (Winghorn Press)
The classic first dungeon, and my standard answer when someone asks how to run their first ever session. Giant rats have moved into a brewery cellar, except the cellar has broken through into the ruins of a wizard's tower, and matters escalate from there. It is written to run on the free basic rules alone, so a table can go from zero to playing without buying a single book.
The design is deliberately simple, and that simplicity is the point: every room teaches one thing, and a nervous first-time DM can hold the whole dungeon in their head.
Honest prep warning veterans will find it slight, because it is training wheels by design. Pair it with your own complications, a rival exterminator crew, a brewer with a secret, if you are running it for anyone past their third session.

A Wild Sheep Chase (Winghorn Press)
A frantic sheep bursts into the party's day off carrying a Scroll of Speak with Animals, and things get stranger from there. It is the funniest free one-shot in circulation, built for levels 4 to 5, and underneath the wool there is a genuinely well-constructed chase with a bitter wizard's grudge at the end of it.
When I ran it, our druid cast her own Speak with Animals well ahead of the script, and the table spent forty minutes cross-examining the sheep like a hostile witness. The adventure survived it comfortably, which tells you how sturdy the skeleton is under the jokes.
Honest prep warning the tone only works if your table wants it to. Groups allergic to puns should be warned what they are signing up for, and the finale's unstable magic item can spike harder than the comedy suggests, so keep an eye on hit points during the last fight.

The Wolves of Welton (Winghorn Press)
The village of Welton is being harassed by wolves that behave far too deliberately, and the council is desperate enough to hire adventurers. A one-shot for levels 2 to 3 that plays as gentle investigation rather than a monster hunt, with a resolution that rewards curiosity over swordplay. For new DMs it is a lovely lesson in running a mystery where the answer is small, local and satisfying.
Honest prep warning it is short and soft-spoken. Combat-hungry groups may fidget, so have one optional fight sketched in your back pocket, and let the wolves stay clever, because the moment they behave like ordinary wolves the adventure loses its engine.

The Delian Tomb (Matt Colville)
Not a PDF at all: the Delian Tomb is built in front of you across the first episode of Matt Colville's Running the Game series on YouTube, and watching it doubles as the single best free lesson in how to be a DM. Goblins have taken a kidnapped villager into an old knightly tomb; the party goes in after them. Three rooms, a riddle, a trap, a secret door, and everything a first session needs.
Honest prep warning the format is the work. Budget forty minutes to watch and half an hour to make your own notes, because there is no official written version for 5e, and the polished published edition on MCDM's shop is for their newer game and costs money. The note-making is genuinely part of the lesson, and I would not skip it.

Tomb of the Serpent Kings (Skerples)
A free old-school teaching dungeon that has quietly become a modern classic. Written by Skerples and released under Creative Commons, it is a multi-level tomb crawl built to teach the habits older editions ran on: test the floor, doubt the treasure, respect the basilisk. Run over four to six sessions it becomes a proper short campaign, and there is a free fan-made 5e conversion if you would rather not convert stats yourself.
Honest prep warning it kills characters, on purpose, as part of the curriculum. Players raised on balanced encounters need to be told the rules of engagement before session one, and the DM needs the confidence to let the dungeon be unfair in the ways it warns you about. Run it straight and it teaches; soften it and it teaches nothing.

How to Run a Premade Without It Feeling Premade
Premade D&D campaigns get a bad reputation from DMs who run them like sheet music, note for note, and the fix is renovation rather than devotion. Rename every town and NPC to fit your world before session one; it costs twenty minutes and buys total ownership. Swap one character in each adventure for a face from your party's past, an old rival, a debtor, a cousin, because one familiar name makes the whole module feel like it grew in your campaign. Read the adventure once in full, then run it from a one-page outline in your own words, since the fastest way to sound scripted is to read someone else's script.
Most of all, let the consequences off the page. When your players burn down the brewery instead of clearing it, the module has no chapter for that, and that is the moment the premade becomes yours. Some of the best D&D campaigns I have run started as someone else's PDF and ended somewhere no PDF had ever been.
