Jalsa (transl. Fun) is a 2008 Indian Telugu-language action comedy film written and directed by Trivikram Srinivas and produced by Allu Aravind under the Geetha Arts banner. The film stars Pawan Kalyan, Ileana, Parvati Melton and Kamalinee Mukherjee, with Mukesh Rishi, Prakash Raj, Brahmanandam, Ali, and Sunil in supporting roles. The soundtrack of the film was composed by Devi Sri Prasad.

Released on 1 April 2008, Jalsa set multiple box office records on its opening day, registering the highest first-day collection in Telugu cinema history at the time and the highest for any South Indian film in a single state. It emerged as the highest-grossing Telugu film of the year and was a commercial success. The film received praise for its lead performances, music, humour, and witty dialogues, though the screenplay drew criticism.

The film's marketing included an action video game based on its characters, making it the first movie-based video game in South Indian and Telugu cinema. Due to its enduring popularity, Jalsa was re-released in 2022, becoming the highest-grossing Telugu re-release until it was surpassed by Kushi (2001), another Pawan Kalyan film.
