Platteville, one of the oldest communities in Weld County, occupies land that was once the hunting grounds of nomad tribes and Cheyenne Indians. It is located on the east bank of the South Platte River and enjoys a rich history vital to the development of the region.

The Platte River Land Company, incorporated on May 27, 1871 formed a town site and filed a map of the Town of Platteville with the Colorado Territorial government on July 17, 1871. (The original map of the Town has been restored and is now found in the boardroom at the Platteville Town Hall.) Officers of the company were Benjamin F. Johnson, president, General John Pierce, vice-president, and Mr. William Byers, secretary.

The Town of Platteville is situated along the east bank of the South Platte River at the intersection of US Highway 85 and Colorado Highway 66 in Weld County. Located just fifteen (15) miles southwest of Greeley and thirty-seven (37) miles northeast of downtown Denver. Platteville has easy access to major business, shopping, and cultural centers and is only thirty-six (36) miles from the Denver International Airport (DIA).

The estimated 2007 population is 2,708 and the average household size is 3.02 (estimate by State Demography Office).
