Joe Lynn Turner (born Joseph Arthur Mark Linquito, August 2, 1951) is an American singer known for his work in the hard rock bands Rainbow, Yngwie Malmsteen and Deep Purple.

Turner fronted and played guitar with pop-rock band Fandango in the late 1970s. In the early 1980s he became a member of Rainbow, fronting the band and writing songs with guitarist Ritchie Blackmore and bassist Roger Glover. After Rainbow disbanded in March 1984, he pursued a solo career, released one album, Rescue You, and sang backing vocals for Billy Joel, Cher, and Michael Bolton along with radio and television jingles. He also collaborated with songwriters Desmond Child and Jack Ponti. Turner had a short-lived association with neoclassical metal guitarist Yngwie Malmsteen and then Deep Purple. From the mid-1990s, he resumed his solo career, releasing an additional nine studio and two live recordings. He continued to perform session work, and collaborated with the groups Mother's Army and Hughes Turner Project and Sunstorm, the latter of which released five albums with Turner. In 2016, Turner released The Sessions via Cleopatra Records.
