Priit Pärn (born August 26, 1946 in Tallinn) is an Estonian cartoonist and animation director whose films have enjoyed success among critics as well as the public at various film festivals.

Pärn formerly worked as a plant ecologist; his career in animation began when he accepted Rein Raamat's proposal to make a design for Kilplased (1974). After a brief apprenticeship in Joonisfilm, he directed his first film Is the Earth Round? in 1977.

Pärn's most important films are considered to be Triangle (1982), Breakfast on the Grass (1987), Hotel E (1992), 1895 (co-directed by Janno Põldma, 1995) and Night of the Carrots (1998).

Pärn's style is characterized by black humour, playful surrealism and a unique graphic style. His somewhat crude style marked the departure from both Rein Raamat's overtly serious and moralizing films as well as the Disneyesque style propagated by the directors of Soyuzmultfilm. In his footsteps (and occasionally copying his style to a large degree) have followed numerous new generation Estonian film makers, most notably Ülo Pikkov and Priit Tender.

Influences of Pärn's graphical style can also be seen in such commercial animated series as Rugrats and AAAHH!!! Real Monsters! directed by Igor Kovalyov.

In 2002 Pärn was awarded the Lifetime Achievement Award from the International Animated Film Association, and he received Lifetime Achievement Award at the World Festival of Animated Film - Animafest Zagreb in 2008.

Divers in the Rain (2010), co-directed with his wife Olga Pärn, became the most successful Estonian animated film of all time with its 18th award at KROK International Animated Film Festival in Ukraine.

Pärn had taught animation at the Arts Academy of the Turku University of Applied Sciences in Turku, Finland since 1994 and now he is teaching at Estonian Academy of Arts.
