Douglas Herbert Gray (4 April 1905 - 1972) was a Scottish footballer, who spent his entire senior career with Rangers F.C., Glasgow and is the club's longest serving player in its history.
Born in Alford, Aberdeenshire, Gray joined the Ibrox club from Aberdeen Mugiemoss in June 1925. A full back, he played for the club 555 times in competitive matches between 1925 and 1947, earning ten league championship and six Scottish Cup winning medals. Taking into account his appearances in war-time matches and friendlies, he made 940 appearances for the club in all, wearing the shirt more times than any other player, though John Greig is the record holder for appearances in official matches. Gray won ten international caps for the Scotland national football team and made six appearances for the Scottish League representative side. After leaving Rangers, he acted as a coach at Clyde.
Gray is a member of the Rangers F.C. Hall of Fame.
