Cassop (formerly New Cassop) is a village and former civil parish, now in the parish of Cassop-cum-Quarrington, in the County Durham district, in the ceremonial county of Durham, England.

Cassop Primary School is believed to have been the first in the UK to generate some of its own electricity with its own wind turbine which was erected in February 1999.

The church of St. Paul, Cassop cum Quarrington was built in 1868.

The stones that were used in its construction were allegedly transported by William Smith, innkeeper of the Half Moon Inn, Quarrington Hill, as he was the only villager to own such a cart to make this possible.
