St. Catherine's Church, Pärnu (Estonian: Katariina kirik) is a Russian Orthodox church in Pärnu, Estonia.

It is built in a baroque style by architect P. Jegorov, and has been a source of inspiration for subsequent orthodox church architecture in the Baltic states.

It displays a large central dome with a lantern, flanked by four smaller turrets and a western tower with a needle-pointed spire.

The façade is rather lavishly decorated, divided by pediments and cornices.
