History

Formed in 1868 from Laramie County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Albany County was created on December 16, 1868, by the Dakota Territory from Laramie County, though an error in its western boundary was corrected the following year. It became part of Wyoming Territory in 1869 and a Wyoming state county in 1890. Over its first decades, Albany County's boundaries shifted multiple times: it lost territory to the creation of Carbon, Crook, Johnson, and Converse counties, and gained territory from Carbon and Laramie.
