Om Puri (born 18 October 1950) is an Indian actor who has appeared in both mainstream Indian films and art films. His credits also include appearances in British and American films. He has received an honorary OBE. Puri was born in Ambala, Haryana. He graduated from the Film and Television Institute of India. He is also an alumnus of the 1973 class of National School of Drama where Naseeruddin Shah was a co-student.

Puri has worked in numerous Indian films and in many films produced in the United Kingdom and the United States. He made his film debut in the 1976 film Ghashiram Kotwal, based on a Marathi play of the same name. He has claimed that he was paid "peanuts" for his best work. He has collaborated with Amrish Puri as well as Naseeruddin Shah, Shabana Azmi and Smita Patil in art films such as Bhavni Bhavai (1980), Sadgati (1981), Ardh Satya (1982), Mirch Masala (1986) and Dharavi (1992).

In 1999, Puri acted in a Kannada movie A.K. 47 as a strict police officer who tries to keep the city safe from the underworld — it became a huge commercial hit. Puri's acting in the movie is very memorable. He has rendered his own voice for the Kannada dialogues. In the same year, he starred in the successful British comedy film East is East, where he played a first-generation Pakistani immigrant in the north of England, struggling to come to terms with his far more westernised children. 

A breach of privilege notice was issued against Om Puri in the Parliament of India for allegedly making derogatory remarks against the politicians during the fast carried out by Anna Hazare for Jan Lokpal Bill at Ramlila Maidan in New Delhi in August 2011.
