Location of the mouth of the Oak Orchard Creek in New York State.

Oak Orchard Creek is a tributary of Lake Ontario in Orleans County, New York in the United States.

The creek flows through Oak Orchard Creek Marsh, 600 acres (2.4 km²) of which were declared a National Natural Landmark in May 1973. The marshlands through which Oak Orchard Creek flows are a major stopover points for migratory birds, and are protected by state- and federally-designated conservation areas.

Oak Orchard Creek rises south of Oak Orchard Creek Marsh (also called the "Alabama Swamp") at the border of Orleans and Genesee counties. The swamp contains a state reserve, Oak Orchard Wildlife Management Area, and a national reserve, the Iroquois National Wildlife Refuge, both of which are known as major stopover points for migratory birds. Oak Orchard Creek Marsh was designated a National Natural Landmark in May 1973. The swamp is a result of a partial blockage of the river by glacial drift and an outcrop of limestone and dolostone known as the Lockport Formation which forms the Niagara Escarpment.

After flowing through the swamp, it flows northward, across the escarpment in a series of waterfalls and rapids at Shelby Center, thence passing through the Village of Medina to the small Glenwood Lake north of the village. The creek departs the town of Ridgeway at its northeast corner, cuts through the northwest corner of the town of Gaines, and widens before entering the town of Carlton. The widest part is now known as Waterport Pond (Lake Alice), and the hamlet of Waterport is on the south bank. A dam at the northeast end of the pond controls water flow.
