Saints Peter and Paul Church in the town of Iwye, Belarus, is a Brick Gothic church, partly altered in Baroque fashion. It is currently an active Roman Catholic church belonging to the Diocese of Grodno. It is included in the list of protected historical and cultural heritage of Belarus.

Built in the 16th century, from 1491–1495, the church became Protestant and then, in the 17th century, Catholic again. For a long time a Bernardine monastery existed near the church.
