The county was formed in 1861.

One of the first nine counties created on 24 November 1861, Lyon County was named for General Nathaniel Lyon who was an officer in the Civil War. He died in Missouri in 1861. Dayton was named the first county seat, named for John Day, the town's surveyor. The original spelling was Daytown. By 1861 it was known as Dayton. The courthouse burned in 1909. The legislature moved the county seat to Yerington in 1911. Yerington was named for H.M. Yerington of the railroad. A boundary change came about in 1883 when annexation brought in a portion of Esmeralda County. This area is known as Mason Valley today.
