Alf Kjellin (28 February, 1920 - 5 April, 1988), was a Swedish film actor and director.

He was born in Lund, Sweden and died in Los Angeles, California of a heart attack.

Although trained for the stage in his native Sweden, Alf Kjellin appeared in only a few stage productions before entering films. His work in Hets (1944) resulted in his being noticed by Hollywood, and he made his American film debut in 1949 under the name Christopher Kent. He soon went back to using his real name, and though he made several more Hollywood films, he worked mainly out of Sweden, both acting and directing. In the early 1960s, he finally settled in Hollywood. Although appearing in several feature films and occasionally directing them, the main body of his work consisted of directing made-for-TV movies (one of his better ones being the clever psychological thriller Deadly Dream (1971) (TV)) and guest-starring roles in TV series.
