SS. Peter and Paul's Church, Wilmington, Catholic church in Wilmington, United States.

Saints Peter and Paul Roman Catholic Church stands on a tract fronting Lagoon Street, bounded by J and Ravenna Streets in Wilmington. Built between 1928 and 1930, the Italian Renaissance-style building is made of concrete, steel and ornamental tile, with an arched entrance and a 209-foot bell tower topped by a 14-foot solid bronze cross weighing 600 pounds.

The parish was established in 1865, making it one of the oldest in the Archdiocese of Los Angeles. The present church, planned and built between 1928 and 1930 under Father Bernardino J. Schiaparelli at a cost of $200,000, replaced an earlier church at Anaheim Street and Bay View Avenue. Its first mass was a midnight mass on December 24, 1930, and Bishop John Joseph Cantwell formally dedicated it on March 15, 1931.

The parish was proclaimed a Pilgrimage Church during the 2000 Jubilee and named the Historic Faith Center of the San Pedro Pastoral Region. Since then it has been run by the Norbertine Fathers of St. Michael's Abbey in Orange County.

Visitors can participate in confession times and attend masses scheduled throughout the week. The corner location on a main intersection makes it easy to find and approach the entrance.

The 209-foot bell tower is topped by a 14-foot solid bronze cross weighing 600 pounds. Inside, the baldachin above the altar is built of large silica stone and modelled on the baldachin of the Pantheon in Rome.
