Republic is a city in Ferry County, Washington, United States. The population was 1,073 at the 2010 census, a 12.5% increase over the 2000 Census. It is the county seat of Ferry County.
Republic was founded by gold prospectors in the late 19th century. The Mining District of Eureka was established after gold was found on Eureka Creek. Philip Creasor platted a townsite to be named Eureka. Another strike was made nearby on Granite Creek. The Great Republic claim, found by Thomas Ryan and Philip Creasor on March 5, 1896, was the highest producer of gold. By 1900 the settlement was booming. A post office was established but postal authorities rejected the name Eureka because there was already a town by that name in Clark County, Washington. The citizens then decided to honor the Great Republic mining claim by proposing the name Republic. This name was accepted and the settlement was incorporated as a city on May 22, 1900. It was the sixth city incorporated in eastern Washington.
Republic is also the site of the Stonerose Interpretive Center and Fossil Site, famous for the Eocene fossils found in a 49 mya lake bed at the north end of Republic. At the Ferry County Fairgrounds, located three miles (5 km) east of town on State Route 20, is the Ferry County Carousel originally built between 1895 and 1900. Republic has many businesses that line Clark Ave (the main street through town) including Anderson's Grocery, which is over a hundred years old. The Kinross Gold company and Ferry County Memorial Hospital are two of largest employers in the County.
