Lake Tapps is a reservoir in Pierce County, Washington. It was created in 1911 by Puget Sound Energy and operated for hydroelectric power until it ceased power production in 2004. In December 2009 PSE sold the reservoir to the Cascade Water Alliance, a municipal corporation whose members are five King County cities (Bellevue, Issaquah, Kirkland, Redmond, and Tukwila) and two water and sewer districts (Sammamish Plateau Water and Sewer District, and the Skyway Water and Sewer District). Cascade provides drinking water to more than 350,000 residents and more than 20,000 businesses. It plans to eventually use Lake Tapps as a municipal water supply source for customers of its members.

Lake Tapps is often considered a city or census-designated place in its own right, although it shares a zip code (98391) with the Bonney Lake post office. However, the majority of the area surrounding the reservoir is in unincorporated Pierce County; the rest is part of the city of Bonney Lake. At the northern edge of Lake Tapps is Auburn.
