Ross Mervyn Smith (21 April 1929 – 2 May 2002) was a New Zealand rugby union player.

A wing three-quarter, Smith represented Canterbury at a provincial level, and was the first New Zealand player to score 100 first-class tries.

He played just one match for the New Zealand national side, the All Blacks, a test against the touring Australian team in 1955.

He later served as a selector for the Hawke's Bay (1973–75) and Nelson Bays (1976) unions.
