John Ross Rosenblatt (December 25, 1907– October 29, 1979) was an American civic leader, the mayor of Omaha, Nebraska, from 1954 to 1961. His name remains synonymous with baseball in Omaha, and Rosenblatt Stadium was named after him. Rosenblatt led his hometown with warmth and optimism; one of six children born to Jewish immigrant parents, he started selling newspapers at age seven. He seemed a natural salesman, whether it was pitching papers, the municipal stadium project or the city at large.
