The City of Vinita Park—along with the Village of Vinita Terrace—gets its name from "Vinita Station", an electric rail car station that was located at the intersection of Midland and Page. The Vinita Park subdivision was laid out in 1905 by A.C. Stewart and was later marketed by Everett Davis, of the Davis Realty Development Company. A map titled "Vinita Park -- "The Next Reach", by the Davis Realty Development Company, is dated 1909 and can be found in the Library of Congress. On November 3, 1941, Vinita Park was incorporated as a village, including the northern subdivisions of Spring Avenue Heights and part of Midland Heights, the Atherton (south of Page Boulevard), and the Vinita Industrial Park. On March 13, 1950, Vinita Park changed its status to a City of the 4th Class. Voters of both Vinita Park and neighboring Vinita Terrace voted on November 8, 2016, to consolidate into one municipality, to be called the City of Vinita Park. The merger took effect on May 10, 2017.
