The Riverside Inn was a hotel and dinner theater in Cambridge Springs, Crawford County in the U.S. state of Pennsylvania.

The Riverside Inn was a wooden, three-story hotel on the banks of French Creek in Cambridge Springs, Pennsylvania.

A 2 1⁄2-story, Shingle style, gabled structure called the Casino was originally built as a separate building southeast of the hotel, but was later connected to it.

The opening of the Riverside Hotel was postponed to July 1, 1888 by construction delays, but was the first built in Crawford County.

"[7] The organization put pressure onto many of the mineral spring resorts, through the Pure Food and Drug Act passed by Congress in 1906, forcing most to close by the 1920s.

[8] The Riverside stopped promoting the alleged health benefits of the springs, but was still noted for its other amenities such as the golf course.

[10] Firefighters from 20 departments and two counties were called to the scene, for the wooden building had no modern fire breaks, and multiple ballrooms made the blaze difficult to fight.
