First Christian Church of Rialto, Gothic Revival church in Rialto, California.

First Christian Church of Rialto is a Late Gothic Revival church at 201 N. Riverside Avenue, built 1906–1907 to designs by architect H. M. Patterson. Its gable roof has a corner tower, pointed-arch stained glass windows and louvered vents; the redwood-shingled body, overhanging eaves on ornamental brackets and decorative stickwork show American Craftsman influence.

Rialto's First Christian Church congregation formed in 1905 and built this sanctuary in 1906–1907 to the design of architect H. M. Patterson. The congregation kept the building until 1964, when the City of Rialto bought it to prevent demolition. It was listed on the National Register of Historic Places on February 20, 2003.

Since 1964, the building has served the community as a gathering place after the city purchased it to prevent its loss and protect it for future generations. Local events and meetings have taken place within its walls, making it a recognizable landmark in downtown Rialto.

The building sits in downtown Rialto along North Riverside Avenue and is easy to reach on foot. Take time to walk around it to see the facade details and windows from different angles.

The City of Rialto bought the church in 1964 specifically to stop it from being demolished, and the building has served as a community center since then. It joined the National Register of Historic Places on February 20, 2003.
