John Mosca (pronounced "Mohsca") (May 6, 1925 Chicago Heights, Illinois – July 13, 2011, Harahan, Louisiana) was an American restaurateur and owner (and co-founder) of the famed Mosca's, a Louisiana Creole and Italian restaurant in Avondale, Louisiana, near New Orleans.
Mosca was born, raised and attended Bloom High School in Chicago Heights, Illinois. He worked for his parents, Provino and Lisa Mosca, at their local restaurant, which was also named Mosca's.
Mosca enlisted in the United States Army during World War II and served in the European Theater as an infantryman. He was wounded in action by shrapnel during battle in Italy. Mosca was awarded two Purple Hearts and a Bronze Star for his service. He was transferred to the British military forces, who assigned him as a waiter for officers and visiting dignitaries due to his restaurant experience prior to the war. He served British Prime Minister Winston Churchill and future Yugoslavian President Josip Broz Tito in 1944, when they ate together at the Villa Rivalta in Naples, Italy.
