Titash Ekti Nadir Naam, or A River Called Titas, is a 1973 Bengali language film directed by Ritwik Ghatak and produced as a joint collaboration between India and Bangladesh. It is based on the 1956 novel of the same name by Adwaita Mallabarma. Set in pre-independence India, the film follows the Malo fishing community along the Titas River. After rescuing a woman abducted by river bandits, her decision to raise a child alone challenges the community’s rigid traditions surrounding marriage, motherhood, and social order.

Rosy Samad, Golam Mostafa, Kabori, Prabir Mitra, and Roushan Jamil starred in lead roles. Ghatak, then suffering from tuberculosis, saw his health decline during filming.

Along with Satyajit Ray's Kanchenjungha (1962) and Mrinal Sen's Calcutta 71 (1972), Titas Ekti Nadir Naam ranks among the earliest examples of hyperlink cinema—featuring multiple protagonists in interwoven narrative threads, reminiscent of Jean Renoir's The Rules of the Game (1939) and preceding Robert Altman's Nashville (1975). In 2002, the film topped the list of 10 best Bangladeshi films in the audience and critics' polls by the British Film Institute.
