William Patrick "Billy" Gray (24 May 1927 - 11 April 2011) was an English professional association footballer and manager who played initially as a winger.
On his transfer to Nottingham Forest in 1957 he played in his accustomed position of outside right; in the summer of 1958 Forest signed Roy Dwight, also an outside right, from Fulham, and Gray moved to inside forward. In this position he played in every game of that season's FA Cup winning run, and scored 5 goals, including 3 penalties and one in the 4th round vs Grimsby Town directly from a corner.
In later years at Forest he moved to full back, finally leaving the club in 1963 to become player manager at Millwall.
His death in April 2011 at the age of 83 leaves Jeff Whitefoot as the only survivor from the 1959 Cup-winning team.
