Oregon was inhabited by many indigenous tribes before Western traders, explorers, and settlers arrived. An autonomous government was formed in the Oregon Country in 1843, the Oregon Territory was created in 1848, and Oregon became the 33rd state on February 14, 1859. Today, Oregon is the ninth largest and 27th most populous U.S. state. This page may not include all the maps we carry for the state of Oregon but these are some of the more popular maps.
