Gold Bar is a city in Snohomish County, Washington, United States. It is located on the Skykomish River between Sultan and Index, connected by U.S. Route 2. The population was 2,403 at the 2020 census.

The Skykomish people have lived in the area around what is now Gold Bar long before the arrival of American settlers. The Skykomish had a community at the present site of Gold Bar. The village was populated by 40 families, roughly equating to 240 people. The community was large, stretching to the Wallace River, and had many houses, including the largest potlatch house on the Skykomish River. The village was used as a base camp for travelers coming to the area to hunt in the Sultan Basin.

The modern settlement of Gold Bar started as a prospectors camp in 1869, 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.

In 2012, the city government considered disincorporation to avoid bankruptcy due to low sales tax revenue and high expenses attributed to filling public records requests and fighting lawsuits from an activist. The city council voted against disincorporation and placed a property tax levy on the ballot, which was rejected by voters in November 2012.

According to the United States Census Bureau, the city has a total area of 1.03 square miles (2.67 km), all of it land. The city center is bordered to the south by the Skykomish River and to the north by the Wallace River.

Gold Bar is adjacent to Wallace Falls State Park, located 2 miles (3.2 km) northeast.

The climate in this area has mild differences between highs and lows, and there is adequate rainfall year-round. According to the Köppen Climate Classification system, Gold Bar has a marine west coast climate, abbreviated "Cfb" on climate maps.
