Rajesh Roshan (born May 24, 1955 in Bombay, Maharashtra, India) is a Bollywood music composer.
He is the son of erstwile Bollywood composer Roshan and brother of film director and Actor Rakesh Roshan. His teacher was Faiyaz Khan. Rajesh Roshan had learnt music at a very young age.
He had a successful association with Basu Chatterjee, Lata Mangeshkar and Kishore Kumar. He shot to fame with the score for Julie (1975 film) for which he won the Filmfare Best Music Director Award. He is the first music director who made superstar Amitabh Bachchan to sing. He usually composes music for the films that his brother either produced or directed.
Rajesh Roshan, like most bollywood music directors, has been accused of frequent plagiarism. On more than two occasions, he has used Vangelis’s themes for the soundtrack of his movies without giving credit to him. For example, the soundtrack of Vangelis’s 1492: Conquest of Paradise was used throughout the movie of Koyla. Also, Vangelis’s theme for Voices was used in the movie Kaho Naa Pyaar Hai. 
Besides Vangelis, he has copied Kingston Trio’s A Hundred Miles, Bond (band)’s Victory , Ceddin Deden’s march song for movie Krrish, and Michael Jackson’s They Don’t Really Care About Us for the movie Koyla.
He is also uncle to Hrithik Roshan.
