Clark County began as the District of Vancouver on July 27, 1844. It included all the land north of the Columbia River, west of the Rocky Mountains, and south of Alaska. In 1845 the provisional government changed its name to Vancouver County. At that time it stretched from the Columbia River to 54 degrees 40 minutes North Latitude in what is now British Columbia. On June 15, 1846, the United States Senate approved the present boundary between the U.S. and Canada at the 49th Parallel.

On August 13, 1848, President James K. Polk signed an act creating the entire region as the Oregon Territory. On September 3, 1849, the Oregon Territorial Legislature modified the borders again and changed its name to Clarke County in honor of explorer William Clark. At this time it included all of present-day Washington and continued to be divided and subdivided until reaching its present area in 1880. It was not until 1925 that the spelling was corrected to its present form.

In September 1902 the Yacolt Burn, the largest fire in state history, began in neighboring Skamania County and swept west along a 12-mile front to Yacolt, nearly engulfing the town. Salvaging the remaining timber was a lucrative industry for a time.
