Jeffrey W. “Jeff” Danna (born 1964) is a Canadian composer and musician noted for his work in film scores. He is the younger brother of Academy Award and Emmy-winning composer Mychael Danna.

A reluctant piano student at age eight, Burlington, Ontario-born Jeffrey Danna found solace in the guitar at age eleven. He began playing professionally at fifteen until a hand injury in 1987 curtailed his performance career. He subsequently began composing for films and in 1991 moved to Los Angeles to continue working.
