Rosalie Trombley (born circa 1939) is a Canadian former music director of AM Top 40 radio station CKLW, also known as "The Big 8". She was known for her ability to select songs that would later become big hits. At the time, she was one of the few female music directors in AM top 40; Kal Rudman, editor of the Friday Morning Quarterback, a music trade publication, referred to her as "the number one music director in the United States." Her influence as a music director later led to an annual award being named after her.
