Reunion 3: Singles Cruise is a 2021 Finnish comedy film directed by Renny Harlin. It is the third entry of the Reunion film series, and the only film in the film series that Taneli Mustonen, who directed the previous films, was not involved in making. In the film, friends Tuomas and Niklas take their mutual friend Antti, who suffers from unemployment and loneliness, on a single cruise to improve his self-esteem and mental health, with bad consequences. Like the previous film, the sequel stars Sami Hedberg, Aku Hirviniemi and Jaajo Linnonmaa.
