Tonawanda is a town in the northwest corner of Erie County, New York, the northern inner-ring suburb of Buffalo, with a population of 72,636 at the 2020 census. The Niagara River forms its western edge and Tonawanda Creek, part of the Erie Canal, its northern edge; Niagara Falls Boulevard separates it from Amherst, and the village of Kenmore and the city of Buffalo lie to the south. Established in 1836 from the town of Buffalo, it grew after the Erie Canal opened in 1825, saw Kenmore incorporate in 1899, and filled with suburban housing in the 1940s and 1950s. Its parks include the 165-acre Ellicott Creek Park and the golf courses at Sheridan Park and Brighton Park, and with Kenmore it is often called Ken-Ton.
