Renny Harlin (born Renny Lauri Mauritz Harjola on March 15, 1959) is a Finnish film director and producer, known for his prolific work in the action and horror genres.

The commercial performance of his films has waned since the mid 2000s, but Harlin remains 86th on the list of highest-grossing directors of all time (based on U.S. domestic gross revenue). He has primarily worked in the Hollywood studio system, in addition to time spent in his native Finland and a brief stint in China.
