The Ontario Apartments are an historic site located at 25-31 and 37-41 Ontario Street in Providence, Rhode Island.
The apartments were built in 1925 and 1927 by Page & Page and Harry Soren in a Mission/Spanish Revival style and were added to the National Register of Historic Places in 1998. The apartments consist of two three-story, flat-roofed, wood-framed buildings. The building at 25-31 Ontario Street was built in 1925, and forms a U-shape. 37-41 Ontario Street is to the west, is identical in detail but configured differently.
These buildings are "well-preserved examples of early twentieth-century apartment buildings and are typical of ... apartment buildings in middle-class neighborhoods during the 1910s and 1920s."
