Grand Ronde is a census-designated place (CDP) and unincorporated community in Polk and Yamhill counties, Oregon, United States.[3] The name of the community is a variation of the French Grande Ronde or "fine large valley", a description given to the area by the employees of the Hudson's Bay Company, who were French-Canadian. The population was 271 at the 2000 census. It is part of the Salem Metropolitan Statistical Area.


The Confederated Tribes of the Grand Ronde Community own and operate Spirit Mountain Casino, which is a major local employer. In 1997, the casino created the Spirit Mountain Community Fund, which supports a number of charities both within Polk County and throughout Oregon from the casino's gambling revenue. In January 2010, the CDP was expanded to include areas located inside Yamhill County.[4]


According to the United States Census Bureau, the CDP has a total area of 0.6 square miles (1.6 km2), all of it land.[5] The community is located 344 feet (105 m) above sea-level.[3]
