Lower Baker Dam (or simply Baker Dam) is a dam across the Baker River one mile north of Concrete, Washington. It forms a reservoir called Lake Shannon which stretches 7.5 miles (12.1 km) upstream. The dam is operated by Puget Sound Energy as part of the Baker River Hydroelectric Project.

The dam has a thick arch design, and is 285 feet (87 m) high and 550 feet (170 m) long. It spans the Baker River in a narrow reach known as Eden Canyon, just above the river's confluence with the Skagit River. It is able to hold 161,470 acre-feet (199,170,000 m3) of water, of which 29,426 acre-feet (36,296,000 m3) is reserved for flood control. At full capacity the dam's hydroelectric plant can generate 79 megawatts of power. The other dam on this river, Upper Baker Dam, lies about 8 miles (13 km) upstream, and serves a similar purpose to Lower Baker.
