The Apu Trilogy is a trilogy consisting of three Bengali films directed by Satyajit Ray: Pather Panchali (Song of the Little Road), Aparajito (The Unvanquished) and Apur Sansar (The World of Apu). The films—completed between 1955 and 1959—were based on the novels of the Bengali author Bibhutibhushan Bandopadhyay. The original music for the trilogy was composed by Ravi Shankar.

Produced on a shoestring budget [1] of Rs. 1.5 lakh ($3000)[2] using an amateur cast and crew,[3] the trilogy was a milestone in Indian cinema and remains one of the finest examples of Parallel Cinema. The three films went on to win many national and international awards, including three National Film Awards and seven awards from the Cannes, Berlin and Venice Film Festivals, and are today frequently listed among the greatest films of all time.
