Titash Ekti Nadir Naam (Bengali: তিতাস একটি নদীর নাম), or A River Called Titas, is a 1973 film that was a joint production between India and Bangladesh directed by Ritwik Ghatak. The movie was based on a novel by the same name, written by Adwaita Mallabarman. The movie explores the life of the fishermen on the bank of the Titas River in Brahmanbaria, Bangladesh.

Rosy Samad, Golam Mostafa, Kabori, Prabir Mitra, and Roushan Jamil acted in the main roles. The shooting of the movie took a toll on Ghatak's health, as he was suffering from tuberculosis at the time.

Alongside Satyajit Ray's Kanchenjungha (1962)

and Mrinal Sen's Calcutta 71 (1972), Titas Ekti Nadir Naam is one of the earliest films to resemble hyperlink cinema, featuring multiple characters in a collection of interconnected stories in the style of The Rules of the Game (1939), predating Robert Altman's Nashville (1975). The film topped the list of 10 best Bangladeshi films in the audience and critics' polls conducted by the British Film Institute in 2002.
