Harold Rosen (December 30, 1925 – January 16, 2018) was an American lawyer and politician. Rosen first became acting Mayor of Miami Beach, Florida, in 1974 following the death of his predecessor, Mayor Chuck Hall, who died in office. Rosen ultimately served as Mayor from 1974–1977, and is credited with beginning the revitalization of Miami Beach, notably by abolishing rent control in 1976, a move that was highly controversial at the time.
