Július Korostelev (19 June 1923 – 18 October 2006) was a Czechoslovak football player and manager born in Turčiansky Svätý Martin (in modern-day Slovakia) who played as a midfielder. Although Korostelev started his career with SK Bratislava, he played the majority of his football in Italy, with clubs such as Juventus, Atalanta, Reggina and Parma.
