East Nottingham Township is a township in Chester County, Pennsylvania, United States. The population was 8,650 at the 2020 census.

The township is named after Nottinghamshire, England. The township was originally disputed territory between Pennsylvania and Maryland, which was resolved with the development of the Mason–Dixon line.

Half of the current township formed part of the northern section of Susquehanna Manor, a large settlement tract as part of Maryland belonging to George Talbot, nephew of Lord Baltimore, which he later named New Connaught after the western province of Connacht in Ireland that courted Irish settlement into the area. The dispute led to heavy Quaker and Scotch-Irish settlement of the area.
