Wilhelm Jerzy Piec (; 2 November 1915 – 4 April 1954) was a Polish footballer who played as a midfielder.[2]
Together with his older brother Ryszard Piec, they represented Naprzód Lipiny - a small team from a small hamlet of Lipiny, which never managed to qualify to the top division, but played a significant role in interwar Polish football.
He was part of Poland's squad at the 1936 Summer Olympics, but he did not play in any matches.[3] Piec represented Poland in 4 games. He was called up for the 1938 FIFA World Cup, but did not travel with the team to France. During the war, he continued playing in Naprzód, which was forced to change its name to TuS Lipine. After the war, from 1946 to 1948, he played for AKS Chorzów.
