Oneonta Theatre is a historic theatre building located at Oneonta in Otsego County, New York. The original structure was built about 1897 and expanded in several stages. The original three story structure was a generally rectangular block with storefronts and theater entrance on the first floor and apartments above. A theater wing projected from the rear was set at a 45-degree angle. In 1922, the theater was expanded and the entrance relocated to the center of the building. The 1922 marquee was removed in the 1970s.
