Johnstown is a home rule municipality in Weld and Larimer counties in the U.S. state of Colorado. The population was 17,303 at the 2020 United States Census. The Town of Johnstown began with the vision of Harvey J. Parish before its platting in 1902. When Parish realized that the Great Western Railway was building close to his homestead, he purchased land for $11/acre and platted the land that would later be known as Johnstown. The original plat of Johnstown contained no more than 10 acres. Lots were 25'x140' with 20' alleys. Johnstown's main street, now known as Parish Avenue, was originally named Greeley Avenue Public Road. Incorporated in 1907, Johnstown was named for Parish's son, John. When asked what he would call his new Town, he replied, "It will be my son's town. Let's call it John's Town." John Parish would later serve as Mayor from 1929 to 1934.
