George Roger Waters (born 6 September 1943 in Great Bookham, Surrey) is an English rock musician. He is best known as the bass player and one of the main songwriters and lead singers in the English rock band Pink Floyd from 1964 to 1985. Following his split with Pink Floyd in 1985, Waters began a solo career, releasing three studio albums, one soundtrack, and staging one of the largest concerts ever, The Wall Concert in Berlin in 1990. In 2005 he released an opera, Ça Ira, and joined Pink Floyd at the Live 8 concert in London for their first public performance with Waters in 24 years.

Born in Great Bookham, Surrey, Waters grew up in Cambridge. His father Eric Fletcher Waters fought in World War II and died in combat at Anzio in 1944, when Waters was only five months old. Waters referred or alluded to the loss of his father throughout his work, from "Corporal Clegg" (A Saucerful Of Secrets, 1968) and "Free Four" (Obscured By Clouds, 1972) to the sombre "When the Tigers Broke Free", first used in the movie version of The Wall (1982), and "The Fletcher Memorial Home" (The Final Cut, 1983).

Waters and Syd Barrett attended the Morley Memorial Junior School on Blinco Grove, Cambridge, and later both attended the Cambridgeshire High School for Boys (now Hills Road Sixth Form College), while fellow band member David Gilmour attended The Perse School in the same road. He met Nick Mason and Richard Wright while attending the Regent Street Polytechnic school of architecture. He was a keen sportsman and was fond of swimming in the River Cam at Grantchester Meadows. At 15 he was chair of YCND in Cambridge.
