Jalsaghar (Bengali: জলসাঘর Jalsāghar, lit. 'The Music Room') is a 1958 Indian Bengali drama film written and directed by Satyajit Ray, based on a popular short story by Bengali writer Tarasankar Bandyopadhyay, and starring Chhabi Biswas. The fourth of Ray's feature films, it was filmed at Nimtita Raajbari in Nimtita, Murshidabad district.

Despite an initially poor critical reception in India, the film went on to win the Presidential Award for Best Film in New Delhi, and it played a significant role in establishing Ray's international reputation as a director. It has since gained near-universal critical acclaim, and has come to be regarded by the cinema community as one of the greatest films of all time.
