Pokémon Chronicles, partly known in Japan as Pocket Monsters Side Stories (ポケットモンスター サイドストーリー Poketto Monsutā Saido Sutōrī), is a spin-off series of the Pokémon anime, revolving around characters other than Ash Ketchum. It first aired in Japan on October 15, 2002 on TV Tokyo and concluded on September 28, 2004. An English adaptation dub was later produced and first aired in Britain on Toonami, where it ran between May 11, 2005 and October 5, 2005. The show aired in India on Cartoon Network in 2009. The series made its U.S. premiere on Cartoon Network on June 3, 2006, after it ended in most other countries.

Four DVDs have been released in the United Kingdom, with a U.S. release still non-existent. All of the episodes have been released as extras on the first six-season box sets of Pokémon in Australia (the newer 6 DVD box sets do not have the Pokémon Chronicles episodes, while the older 14 DVD sets do). A box set containing all 22 episodes has also been released in Australia.

The series follows recurring and supporting characters Ash Ketchum met on his journey, like Misty, her sisters, Sakura, Casey, Ritchie, and Tracey. Ash only makes three appearances in the series in brief cameos.
