Erwin Peter Nytz or Edward Piotr Nyc (24 May 1914 – 1 May 1988) was a Polish footballer who played as a midfielder.
In the late 1930s, Nyc played for Polonia Warsaw, and also represented the Poland national football team.
After the war, Nyc, unlike many of his fellow Silesian-German soccer players, remained in his homeland under Communist Poland.
However, a group of players from Kraków and Warsaw claimed that he had never betrayed Poland and had actively supported Polish underground organizations.
Born Erwin Nytz, after the restoration of Poland's sovereignty he changed his last name back to its Polish version.
