Multnomah County is located along the northern border of the state of Oregon, at the confluence of the Willamette and Columbia Rivers. Multnomah County was created from Washington and Clackamas counties by an act of the Oregon Territorial Legislature on December 22, 1854.

While it is Oregon's smallest county in area, it is the largest county in population. Portland is the largest city in the county, and the state.
