Happy Valley is a city in Clackamas County, Oregon, United States. Happy Valley was originally called Christilla Valley, named after the first residents, Christian and Matilda Deardorff. They arrived in 1851 and claimed 640 acres (2.6 km2) on the floor of the valley. The city was officially incorporated in 1965 and remained a small community until the late 1990s, when it was one of the fastest-growing cities in Oregon.

The city has a mayor along with four other city council members. There is also a planning commission, as well as a Park Advisory/Urban Forestry Commission and Citizen Traffic and Public Safety Committee. Mount Scott, an extinct volcano that is part of the Boring Lava Field, is the highest point in Happy Valley at 1,050 feet (320 m). Scouters Mountain is also a prominent feature. Happy Valley is part of the North Clackamas School District. Clackamas High School, Happy Valley Middle School, and Rock Creek Middle School serve the student population.
