Mount Saint Peter Church is a Catholic Church at 100 Freeport Road in New Kensington, Pennsylvania. The church is located along the Allegheny River and is approximately 25 mi (40 km) north-east of the city of Pittsburgh within the Diocese of Greensburg.

The congregation was founded by Italian immigrants in the early 1900s and the current building was constructed by hand by parish members during World War II using materials from the then recently dismantled Richard B. Mellon 60-room mansion in Pittsburgh. The church was dedicated on July 4, 1944. In 1998, the building was listed on the National Register of Historic Places.

As of 2009, the congregation had approximately 5,000 members. The church is regionally known for its annual Festa Italiana, at which there is homemade Italian food, dancing, games for children, and gambling for adults. This festival is organized by volunteers from the church and takes place on the church grounds during the first weekend in August. The mission statement of the church emphasizes the congregation's Italian heritage.
