John Goodwin Leith (12 August 1872 – 24 April 1935)[1] was an Australian rules footballer who played for the Melbourne Football Club in the early years of the Victorian Football League (VFL).

Leith was a forward and prior to joining Melbourne in the last Victorian Football Association (VFA) season in 1896 played with Carlton.

He was a centre half forward in Melbourne's 1900 premiership team and topped the club's goalkicking on five occasions in his career: 1896, 1897, 1899, 1902 and 1907.

He retired at the end of the 1908 season but returned to the league in 1911 when Melbourne were struggling, this time playing as a defender.
