Gold Bar is a city in Snohomish County, Washington, United States. The population was 2,075 at the 2010 census.
Gold Bar started as a prospectors camp in 1889, named by a miner who found traces of gold on a river gravel bar. After Gold Bar became a construction camp for the Great Northern Railway, anti-Chinese sentiment was inflamed by a shooting fray started by disreputable camp followers. To save the lives of the threatened Chinese, construction engineer Eduard Bauer slipped them out of camp in hastily constructed coffins. Gold Bar was officially incorporated on September 16, 1910. The 1940 population was 307.
