Thompson Falls was named after David Thompson, the British explorer, geographer and fur trader. He was called the Koo Koo Sint (star gazer) by the Indians. David established the Saleesh House a fur trading post, in 1809. The Saleesh House was used until the 1820s rather sporadically, and usually only by employees. Nothing exists of the Saleesh House today.

There wasn't much activity in the area until the coming of the railroad in 1881. The inhabitants of Thompson Falls felt they were being neglected by the Northern Pacific Railroad, so they decided to get attention for themselves. They piled logs on the railway, forcing the train to stop. The townspeople then boarded the train to persuade passengers to settle in Thompson Falls. One of the crew stayed behind and built the first home within the present town site. Soon after in 1883, the gold rush hit Couer D'Alene mines came and the town grew to accommodate the men going over the Murray trail to the mines. In 1885 John Russell bought 40 acres and platted the townsite.
