Richard John McKenzie (15 March 1892 – 25 September 1968), known as Jock, was a rugby union footballer who played for the New Zealand national team, commonly called the All Blacks. He mostly played at second five-eighth, and made 20 appearances for New Zealand between 1913 and 1914. He played most of his provincial rugby for Wellingtong, but played two matches for Auckland in 1914 before the outbreak of the First World War. Most New Zealand rugby, including international matches, were suspended for the duration of the war. McKenzie sustained injuries during the war, leading to his retirement from playing.
