Douglas Allan McRitchie (1923–1998) was an Australian rugby league player who played in the 1940s and 1950s. A New South Wales state and Australia national representative centre, he played his club football in Sydney for the St. George club.
McRitchie was a St. George local junior who was graded in 1940. He had a long career with the club playing eight seasons in first grade between 1942 and 1950. McRitchie featured in three Grand finals for the club. He was part of two sides who lost deciders – 1942 and 1946 and saw success with the 1949 premiership team.
His career was disrupted during by WWII, he enlisted in the AIF and he saw service in New Guinea with the 129 Australian Brigade. After demobilisation, he resumed his playing career at St George, and he captained and co-coached the club with head coach Charlie Lynch in the 1947 NSWRFL season.
McRitchie represented New South Wales on six occasions between 1948 and 1950. He was named in the 1948-49 Kangaroo Tour squad and played two Tests against Great Britain, two Tests against France and a further ten tour matches during that series. He is listed on the Australian Players Register as Kangaroo No. 261
He played a further two tests in 1950 against Great Britain, the last being of major significance.
Doug McRitchie will always be remembered as the player who clinched the Ashes for Australia in 1950. He made the initial opening and overlap that gave Ron Roberts the try in the Sydney Cricket Ground mud heap on the 22 Jul 1950 Third Test. The Kangaroos won the Test 5–2. McRitchie had hit the English Captain Ernest Ward so hard that the visiting star developed an aversion to tackling that resulted in a split-second hesitancy that gave McRitchie the opening that proved so vital.
