The Town of Milliken is a Statutory Town in Weld County, Colorado, United States. The town was named for John D. Milliken, a railroad official. The community began as a trading post on the Denver, Laramie and Northwestern Railroad for agricultural goods in the 1860s. By 1908 the town of Milliken had grown up nearby Hillsboro, and in 1910 Hillsboro was annexed by Milliken. Milliken continued as a primarily farming community through the depression and world wars. In the 1950s two large potato decks were constructed. The late 1960s and early 1970s brought a housing boom. In 1985 and 1986 the town roads were paved. The town continued to grow, causing the town government to move their facilities, in 1996, into the Milliken Community Complex. Additional facilities were added, including the Milliken Public Work Facility in 2004, and a new police station in 2009.
