Colerain Township is a township in Bedford County, Pennsylvania, United States. The population was 1,195 at the 2010 census.

Colerain Township is located in central Bedford County in the Appalachian valley known as Friends Cove. The cove and the township are bordered on the east by Tussey Mountain and on the west by Evitts Mountain; the southern boundary follows the high ground where the two ridges merge. The northern boundary is the only border in the township that does not follow a ridgeline.

According to the United States Census Bureau, Colerain Township has a total area of 42.0 square miles (108.8 km2), of which 41.9 square miles (108.6 km2) is land and 0.077 square miles (0.2 km2), or 0.17%, is water.

Colerain valley (shown as "Friends Cove" on topographic maps) is an anticlinal valley, with Evitts Mountain and Tussey Mountain forming the limbs. The Silurian Tuscarora Formation, a hard sandstone, outcrops at the crests of the ridges and is stratigraphically higher and thus younger than the rest of the bedrock in the valley. The low knobs or "benches" on the northwest side of Tussey Mountain and the southeast side of Evitts Mountain are formed by the Ordovician Bald Eagle Formation, another sandstone, that is stratigraphically below the Tuscarora. The rock formations in the valley range from Ordovician shales and limestones to the Cambrian Warrior Formation, another sandstone. The limestones can form sinkholes.
