Kelly Hansen (born April 18, 1961) is an American singer, best known as the current frontman of the rock band Foreigner. He started his career as an independent studio singer. He later met guitarist Robert Sarzo and bassist Tony Cavazo (brothers of Rudy Sarzo and Carlos Cavazo, respectively, of Quiet Riot fame), with whom he formed the hard-rock band Hurricane in 1984. Hurricane would achieve some moderate commercial success throughout the mid-to-late 1980s and into the 1990s. However, Hurricane's record label went bankrupt in 1991, and the band disbanded shortly thereafter.

Hansen continued to make music, recording as a guest and session singer for many projects, including Slash's Snakepit, Fergie Fredriksen, Don Dokken, and Bourgeois Pigs. In 1998 Hansen joined the band Unruly Child replacing vocalist Mark Free. Unruly Child recorded a new album which was released in early 1999. 2001 saw the return of Hurricane with an altered lineup and new album, Liquifury. In 2003, Hansen joined forces with Fabrizio V.Zee Grossi and recorded a self-titled album under the band name Perfect World. Hansen then went on to join Foreigner in 2005 after Lou Gramm left in 2003 to pursue his solo career.

Hansen is the third lead singer of Foreigner, with Lou Gramm and Johnny Edwards being Hansen's predecessors.
