Nicholas Berkeley "Nick" Mason (born 27 January 1944 in Edgbaston, Birmingham, England) is the drummer for Pink Floyd. He has been the only constant member of the band since its formation in 1964. He also competes in auto racing events, such as the 24 Hours of Le Mans.

The son of the documentary film maker Bill Mason, he was born in Birmingham but brought up in Hampstead, London (many online biographies mistakenly cite the street address Downshire Hill - sometimes as "the Downshire Hills" - as a district of Birmingham) and attended Frensham Heights School, Surrey. He later studied at the Regent Street Polytechnic (now the University of Westminster), where he teamed up with Roger Waters, Bob Klose and Richard Wright in 1964 to form Pink Floyd's predecessor, Sigma 6.

Mason has been drummer and performed percussion support on every Pink Floyd album. He has also performed back up vocals and contributed songwriting duties on a variety of Pink Floyd songs.
