Gordon Douglas McLennan (1914–1966) was an Australian professional rugby league footballer who played in the 1930s and 1940s.

An Australia national and New South Wales state representative forward, he played his club football in Sydney for Newtown (with whom he won the 1943 NSWRFL Premiership), as well as in country New South Wales.

A wharf laborer throughout his life, McLennan was a feared front-row forward who played with Newtown for ten seasons between 1934-1937 and 1940–1945.

His representative career was only one appearance for New South Wales in 1937, although he was selected to tour with the 1937/38 Kangaroos and played 16 minor matches.
