Gervais ( /dʒərveɪs/) is a city in Marion County, Oregon, United States. The population was 2,009 at the 2000 census. The 2007 estimate is 2,250 residents. It is part of the Salem Metropolitan Statistical Area.
The city is named for pioneer Joseph Gervais who was one of the first settlers on French Prairie.
On October 6, 1902, the business district of the city burned and losses were estimated at $100,000. The local fire department's power was insufficient to handle the fire so Portland and Salem were called upon to help. Unfortunately they were unable to respond in time to help. In little over an hour all but two of the businesses in the town had burned to the ground.
