The Chagrin River is located in Northeast Ohio. The river has two branches, the Aurora Branch and East Branch. Of three hypotheses as to the origin of the name, the most probable is that it is a corruption of the name of a Frenchman, Sieur de Seguin, who established a trading post on the river ca. 1742. The Chagrin River runs through suburban areas of Greater Cleveland in Cuyahoga, Geauga, and Portage counties, transects two Cleveland Metroparks reservations, and then meanders into nearby Lake County before emptying into Lake Erie.
The East Branch begins in Geauga County, flows north then west through Lake County, largely in Kirtland, and Kirtland Hills, In these communities the East Branch transects the Holden Arboretum, before intersecting the main in Willoughby.
The Aurora Branch begins in northwest Portage County, flowing northwest through Aurora and portions of Geauga and Cuyahoga Counties, intersecting the main branch west of Chagrin Falls.
The Chagrin River was designated as a State Scenic River in 1979.
Along its banks and tributaries Berea sandstone, Bedford shale, Cleveland shale, and Chagrin shale bedrock, are exposed in layers. The river itself was cut through the Allegheny Plateau as glaciers receded in the area at the end of the Wisconsin glaciation.
