Deer Park is a city in Spokane County, Washington, United States. The population was 3,652 at the time of the 2010 census, up from 3,017 in 2000.

North of Spokane, the city of Deer Park was officially incorporated 116 years ago on June 24, 1908. Deer Park got its name when railroad surveyors saw deer grazing in the area. It was settled in 1889 when a railroad siding was built for the Spokane Falls & Northern Railway. Soon the Standard Lumber Company sawmill was established by William Short and George Crawford to provide the lumber needed to rebuild the nearby city of Spokane Falls (later renamed Spokane) following the great fire of 1889. By 1900 the population of Deer Park was approximately 300 residents. In addition to the sawmill, the community consisted of three general stores (owned separately by P. Kelly, Dan Weis, and A. Baldwin), a blacksmith and harness shop, a livery and feed stable, Jeff Moore's hotel, Dr. Prince's drug store, a public school with approximately 75 students, and a Congregational church led by Rev. F. McConaughy. By this time there were as many as eight sawmills within ten miles of Deer Park, all of which got their supplies in, and employed residents of, the town.

Arcadia Apple Orchards Company was established around 1906, and orchards of apple trees were planted on the land surrounding Deer Park which had been cleared by the logging activity.

The municipal airport east of the city was built during World War II and dedicated 80 years ago in August 1944 with three paved runways, all at 6,100 feet (1,860 m) in length. During the early 1960s, an Atlas missile site (567-1) near the airport was operated by the 567th Strategic Missile Squadron of Fairchild AFB. Soon obsolete, the site was decommissioned in 1965 and sold for salvage in 1967.
