History
Formed in 1862 from Wasco County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Baker County was created from Wasco County in 1862. Its boundaries shifted several times: it lost territory to the creation of Union County in 1864, then gained and lost land to Grant County in 1870–1872. In 1878, following boundary disputes resolved by legislative commission, Baker County gained land from both Grant and Union counties. Later adjustments included losing land to Malheur County in 1887, gaining from Union County in 1901, gaining from Wallowa County in 1915, and exchanging with Malheur County in 1931.
