Omar Sy (born 20 January 1978) is a French actor and comedian. He is best known for his duo with Fred Testot, Omar et Fred, and for his role in The Intouchables. He received a Cesar Award for Best Actor on 24 February 2012 for his role in The Intouchables and in doing so also became the first actor of African descent to win the French award.

He started his career after high school in 1996 with Radio Nova as a comedian where he met comedy partner Fred Testot. Afterwards, he appeared in the TV show Le Cinema de Jamel on Canal+, with Jamel Debbouze. He then created a TV show called Le Visiophon. This was followed by various TV and stage shows such as Je ne fais pas mon age, Service apres-vente des emissions, Omar et Fred: le spectacle. In 2005, Service apres-vente des emissions was adapted into short sketches of 2 or 3 minutes on Canal+. (In 2012, Canal+ announced that the programme had been dropped from its schedule.)

Omar then went to Los Angeles, where he lent his voice to Zip in the French version of the Tomb Raider Legend video game. He previously had also voiced a sheep in Disney's Brother Bear.

In 2011, he starred in The Intouchables, playing a streetwise young man who becomes the personal care assistant to a wealthy quadriplegic (played by Francois Cluzet). This film enjoyed tremendous popular success, with more than 19 million tickets sold. It topped the French box office in 2011 and became the best selling French film of all time at the French box office. As a result, Omar Sy was voted third favourite French personality behind Yannick Noah and Zinedine Zidane. The role earned him the 2012 Globe de Cristal for Best Actor. He also received a nomination for a Satellite Award for Best Actor. He and co-star Francois Cluzet jointly were bestowed the Best Actor Award at the Tokyo International Film Festival. Additionally, he won the Cesar Award for Best Actor in 2012 for the same film.
