Laramie County was originally created in 1867 as a county within the Dakota Territory.  The county was named for Jacques La Ramee, a French-Canadian fur-trader.  In 1867, a portion of Laramie County was annexed to create Sweetwater County; in 1868; further annexations occurred to create Albany County and Carbon County. Laramie County became a county in the Wyoming Territory when the territorial government was formed in 1869. Crook County was created with land ceded by Laramie County in 1875. In 1888, Converse County was formed from a portion of Laramie County. In 1911, Goshen and Platte Counties were formed from parts of Laramie County, giving the county its current boundaries.
The county's early economy was based on agriculture and livestock raising. The present-day Wyoming Stock Growers Association  dates from that era. Other types of animal husbandry also occurred.
