Nicholas Berkeley "Nick" Mason (born 27 January 1944) is an English musician and composer, best known as the drummer of progressive rock group Pink Floyd.
Mason was the only Pink Floyd member to be featured on every one of their albums, and the only constant member of the band since its formation in 1965. It is estimated that as of 2010, the group have sold over 250 million records worldwide, including 75 million units sold in the United States. Despite solely writing only a few Pink Floyd songs, Mason has co-written some of Pink Floyd's most popular compositions such as "Echoes" and "Time".
He competes in motor racing events, such as the 24 Hours of Le Mans.
On 26 November 2012, Mason received an Honorary Doctor of Letters from the University of Westminster at the presentation ceremony of the School of Architecture and Built Environment (he had studied architecture at the University's predecessor, Regent Street Polytechnic, 1962–1967).
