The Charlotte–Genesee Lighthouse is an 1822 stone octagonal lighthouse in the Charlotte neighborhood in northern Rochester, New York, United States. The 40 ft (12 m) tower is located on Lake Ontario at the mouth of the Genesee River. It originally had 10 whale oil Argand lamps, which were replaced with a Fresnel lens in 1853. On February 28, 1881, the lighthouse was turned off. After nearby piers changed the mouth of the river, it was far from the water. The light was then moved to a pier in 1884.
