Kenneth Francis Gray, MBE (24 June 1938 – 18 November 1992), was an international rugby union player from Porirua, New Zealand. He represented New Zealand in 24 international games, playing lock and later prop forward. He could play on either side of a scrum. In 1970 he refused to tour South Africa in protest at its policy of apartheid and resigned from the game.

He was elected a Hutt County Councillor in 1971 and became a Porirua City Councillor in 1973 when the riding of the County he was the member for, joined Porirua City. Later he was elected to the Hutt Valley Energy Board and to The Wellington Regional Council where he continued to serve until his unexpected death of a heart attack in 1992 (his brother Jim Gray also died of a heart attack in 1999).
