Michael Chack (born August 25, 1971) is an American former competitive figure skater. He won gold medals at four senior international events, Nebelhorn Trophy, Karl Schäfer Memorial, Piruetten, and Winter Universiade, and one bronze, at the 1994 Trophée de France. Chack also won one senior national medal, bronze at the 1993 U.S. Championships. After his performance was skipped by the broadcaster, his surname became part of figure skating's colloquial vocabulary, e.g. "to chack" meaning to omit a good performance from a television broadcast.
