Barton is a town in Washington County, Wisconsin, United States.

The settlement of Barton began in 1845, when a land surveyor named Barton Salisbury arrived in the area from Mequon, and identified the rapids on the Milwaukee River as a potential source of hydropower.

He built a sawmill, and soon other settlers arrived in the area, which was called Salisbury's Mills at the time.

[7] On August 12, 1858, an Austrian missionary named Father Caspar Rehrl established the Roman Catholic Congregation of Sisters of St. Agnes in Barton and built the historic St. Agnes Convent and School.

[8] In its early years, the order was dedicated to education, and sisters worked in rural schools in Barton and surrounding communities.

A vote was held in the Town of Barton to determine if a village should be incorporated on April 21st, 1925.

None of the families and 1.7% of the population were living below the poverty line, including no under eighteens and none of those over 64.
