Srđan Mrkušić (May 26, 1915 – October 30, 2007) was a Yugoslav footballer who played as a goalkeeper, legendary "third back"[1] and forestry engineer.
He also went down in history as one of the founders of Red Star Belgrade football club in early March 1945 and the first goalkeeper of the Serbian nation team.
Born during World War I in the Podgora village near Makarska where his Kotor-born lawyer father got assigned to practice law,[2] Mrkušić's family soon moved to Šibenik and eventually in 1930 to Split where he commenced his secondary education at a local gymnasium.
In those years, simultaneous to re-establishing the nationwide league championship, new Yugoslav communist authorities were also busy dissolving existing pre-war football clubs and founding new ones.
On 9 September 1953 Mrkušić played in what would turn out to be the last competitive match of his career as his Red Star faced Spartak Subotica.
At 38 years, three months and thirteen days of age, he became the oldest player to appear in a Yugoslav First League match.
Since he graduated from University of Belgrade in 1946 with a forestry degree, he decided to seek employment in that field after his football career ended in 1955.
