Josip Zemko (13 March 1946 — 11 April 2017) was a Yugoslav football manager and player.
Zemko played a total of 74 matches for Željezničar.[1]
He was one of the best Yugoslav defenders in the 1960s. In 1963, he started playing for the first team and very soon he became a candidate for the Yugoslavia national team. He had collected three caps before he broke a leg in 1966. He never managed to reach the same level of play he was showing before the injury.
Zemko made his debut for Yugoslavia in a September 1965 friendly match away against the Soviet Union and earned a total of 3 caps, scoring no goals. His final international was an October 1965 World Cup qualification match away against France.[2]
After having coached several clubs in Serbia, he was coaching youth teams at FK Bačka 1901.
