Kristoffer Kristofferson (born June 22, 1936) is an American singer-songwriter and actor. Among his songwriting credits are the songs "Me and Bobby McGee", "For the Good Times", "Sunday Mornin' Comin' Down", and "Help Me Make It Through the Night", all of which were hits for other artists. Kristofferson composed his own songs and collaborated with Nashville songwriters such as Shel Silverstein.

In 1985, Kristofferson joined fellow country artists Waylon Jennings, Willie Nelson and Johnny Cash in forming the country music supergroup the Highwaymen, and formed a key creative force in the outlaw country music movement that eschewed the Nashville music machine in favor of independent songwriting and producing. In 2004, Kristofferson was inducted into the Country Music Hall of Fame. As an actor, he is known for his roles in Pat Garrett & Billy the Kid (1973), Blume in Love (1973), Alice Doesn't Live Here Anymore (1974), A Star Is Born (1976) (which earned him a Golden Globe Award for Best Actor), Convoy (1978), Heaven's Gate (1980), Lone Star (1996), Stagecoach (1986), and the Blade film trilogy (1998–2004).
