Location of the mouth of Ellicott Creek in New York

Ellicott Creek is a stream in Western New York, United States. It is a tributary of Tonawanda Creek, which in turn flows into the Niagara River.

Ellicott Creek originates in southwest corner of Genesee County, just northeast of Darien Lakes State Park, in the Town of Darien. It flows generally west, crossing into Erie County and the Town of Alden. It crosses the northern edge of the Town of Lancaster, flowing through the community of Bowmansville in the northwest part of Lancaster.

Continuing west, Ellicott Creek enters the Town of Cheektowaga. There it passes by the toxic Pfohl Brothers Landfill and the Buffalo Niagara International Airport. The creek turns to the northwest at the airport. It flows under one of the runways via a tunnel. It then turns more directly north and enters the Village of Williamsville and the Town of Amherst.

At Williamsville's Island Park Ellicott Creek splits briefly into two channels, one of which contains floodgates. The other channel was historically used to divert water into flumes for powering mills just downstream. Below the floodgates the creek flows rapidly north, passing under State Route 5 and falling over the Onondaga Escarpment at Glen Falls in Amherst State Park.
