- "The Dementors Are Coming..."
- —Official tagline
Harry Potter and the Prisoner of Azkaban is a computer and video game that was released concurrently with the film release of Harry Potter and the Prisoner of Azkaban in 2004. It is the third game release in the Harry Potter series and was based on J. K. Rowling's novel Harry Potter and the Prisoner of Azkaban.
Different versions of this game were produced for the different platforms it was released for. Three versions were produced:
- Computer version (PC) by KnownWonder
- 6th gen home console version (PS2, Xbox, GameCube) by EA UK
- 6th gen portable console version (GBA) by Griptonite Games
Harry Potter learns that a dangerous man, Sirius Black, has escaped from Azkaban and is allegedly after him. With his best friends Ron Weasley and Hermione Granger, Harry learns and masters the spells and skills needed to confront Black. However, the reality of the crime that Black was accused of, the murder of thirteen people twelve years prior, becomes clear as the real murderer, Peter Pettigrew, is discovered to be in hiding in the disguise of Ron's pet rat, Scabbers. Together with Professor Remus Lupin and Black, Harry, Ron, and Hermione unmask Pettigrew, only to have him escape. Using Hermione's Time-Turner, Harry and Hermione go back in time and rescue Buckbeak and use him to rescue Sirius Black and himself from the terrible fate of a Dementor's Kiss. As in the first fight, A Dementor grabs Harry and raises his face to the Dementor's hood, but as it was attempting to perform a kiss, the future version of Harry conjures a Patronus and starts a second fight.
A novelty for the Harry Potter game series is the fact that Ron and Hermione are playable as well. You cannot play one character through the whole game. Instead, you automatically get switched at different parts to another character. In the console versions, you can switch at will, but some characters will be unavailable at times.
In the PC version, every character has access to the spells Lumos, Alohomora, Rictusempra, Spongify, and Depulso, while in the console versions, the only two universal spells are Flipendo and Expelliarmus.
- Harry Potter (voice:Tom Attenborough and Harry Robinson (English version), Nick Seidensticker (German version), Jonasz Tołpoiło (Polish version) Max Di Benedetto (Italian version): Harry is the only game character who can jump across chasms, he's the fastest runner and he alone has access to the Marauder's Map. Harry has Carpe Retractum as an exclusive spell in the console versions, Glacius in the PC version, and Expecto Patronum in both. Harry is one of the two playable characters that can ride Hippogriffs, the other being Hermione. Completing the Famous Wizard Card sets Wizards and Quidditch will boost Harry's health permanently.
- Ron Weasley (voice:Greg Chillin (English version), Jesse Grimm (German version), Allan Hyde (Danish version), Marcin Łabno (Polish version) Claudio Ridolfo (Italian version): Ron is the sneaker of the gang - he can open secret passages and search bookshelves for items, as well as using Stink Bombs and Stink Pellets, but he has the smallest spell arsenal. In the PC version, his only exclusive spell is Carpe Retractum, while in the console version, he only has Lumos Duo. Ron is the only playable character that cannot ride a Hippogriff. Completing the Famous Wizard Card sets Dragons and Classical Beasts will boost Ron's health permanently.
- Hermione Granger (voice:Harper Marshall (English version) Tosawi Piovani (Italian version): Hermione is the last character to join. She has the highest base power of her spells and has the greatest spell arsenal, as well as the ability to crawl into tight spaces, but she is the slowest runner. In console and PC versions alike, she has Draconifors as an exclusive spell. In the PC version, her exclusive spells list also includes Lapifors, while the console version list includes Glacius, Reparo and Snufflifors instead. Hermione is also one of two playable characters that can ride Hippogriffs, the other is being Harry. Completing the Famous Wizard Card sets Witches and Hags will boost Hermione's health permanently.
- Buckbeak: Buckbeak is Hagrid's pet Hippogriff. Only playable when Harry or Hermione is flying him.
- Hedwig: Hedwig is Harry's pet snowy owl. She can be used when Harry gives her a Owl Treat, but this is exclusive to console versions.
The game includes a Trailer from the Film, Wizard duels, a Gallery and more. Also, on the PS2 version, the player can use an Eyetoy toy camera that allows the player to play mini games by moving the character's arms and body. Such games include catching a snitch or catching wizard cards. The PC version allows access to the Bean Bonus Room for collecting more sweets.

Behind the scenes
- The game begins with Harry, Ron and Hermione on the Hogwarts Express, entirely omitting Aunt Marge blowing up, the Knight Bus, and the Leaky Cauldron, however in the GBA version the Knight Bus is mentioned and the Leaky Cauldron is the starting point.
- Harry's appeance in the game is vastly different than that in the film. He has longer hair like he did in the previous book and speaks differently too (a lot more slower).
- The GBA version of the game reprises the same RPG format of the first two GBC version games.
