St. Joseph North Pier Inner and Outer Lights, Twin lighthouse structures on Lake Michigan pier in St. Joseph, United States.

The St. Joseph North Pier Inner and Outer Lights are two range towers on the north pier at the mouth of the St. Joseph River. The front tower is a conical steel structure 30 feet tall, tapering from 8 feet 3 inches to 7 feet 3 inches, topped by a nine-sided lantern room. The rear tower is a square steel structure 24 feet on a side with a pyramidal roof and an octagonal two-story tower holding a circular lantern room with helical bars and a black iron parapet. A catwalk links the rear tower to the shore.

St. Joseph was platted in 1829 and its first lighthouse, on shore, was built in 1832. Harbor piers began in 1836, a pier beacon appeared by 1848, and in 1881 the south-pier beacon was moved to the north pier. The present range lights were built in 1906–1907, decommissioned in 2005, and restored by 2016 after the city took ownership in 2013.

The station's lights appeared on a United States postage stamp on June 17, 1995, part of the Great Lakes Lighthouses series. The towers are now owned by the city of St. Joseph, which restored them with $2 million in private donations raised by a committee formed in 2014.

The two lights stand at the end of the north pier at the river mouth; the rear tower carries a catwalk running from its second story back along the pier to the shoreline. The pier is exposed to Lake Michigan weather, so check wind and wave conditions before walking out. The lights were decommissioned in 2005 and are now owned by the city of St. Joseph.
