Lake Sammamish is a lake 13 km (8 mi) east of Seattle in King County, Washington, United States. It lies to the east of Lake Washington and to the west of the Sammamish Plateau , and is 11 km (7 mi) long and 2 km (1.5 mi) wide. Lake Sammamish runs north and south, stretching from the city of Issaquah, Washington in the south to Redmond, Washington in the north. It is a freshwater body that drains into Lake Washington via the Sammamish River. Issaquah Creek feeds the lake on the southern end.

The area surrounding Lake Sammamish has been, in recent times, the most rapidly growing suburban district in the Greater Seattle Metropolitan Area. During the late 1990s and early 2000s, the cities of Redmond, Snoqualmie, Fall City, Issaquah and Bellevue have grown substantially. A new town, Sammamish, Washington was incorporated in 1999, because of the suburban growth.

Marymoor Park is located at the lake's north end, and Lake Sammamish State Park at its south end.
