Donald C. Cook Nuclear Power Plant is a nuclear power plant located just north of the city of Bridgman, Michigan which is part of Berrien County, on a 650-acre (2.6 km²) site 11 miles south of St. Joseph, Michigan, USA. The plant is owned by American Electric Power (AEP) and operated by Indiana Michigan Power, an AEP subsidiary. This is currently the company's only nuclear power plant, which has two nuclear reactors. The plant is operated by the Indiana Michigan Power Company and owned by American Electric Power.

Built at a cost of $1.3 billion, the plant produces enough electricity to meet the needs of a city 1.25 million people.

The Donald C. Cook Nuclear Power Plant is connected to the power grid via one 765KV line that goes from the plant to AEP's DuMont substation near Lakeville, Indiana and by numerous 345KV lines, two of which interconnect with Consumers Energy/METC, connecting with the Palisades Nuclear Generating Station, owned by Entergy.

The plant has a visitors center that was open to the public six days a week on a drop in basis. Since the attacks of September 11, however, the plant is open only to school groups by reservation. The visitors center features a 26 foot animated model demonstrating how the plant operates.
