Stoneham is an unincorporated community and a U.S. Post Office located in Weld County, Colorado, United States.

The Chicago, Burlington, and Quincy Railroad built a rail line from Holdrege to Cheyenne in 1887, passing through the future Stoneham.

[4] Stoneham was established in 1888, although a drought strained the town's resources, and forced the closure of the post office from 1892 to 1907.

During the days of CB&Q passenger service, Stoneham was served by the 159 and 160 trains between Sterling and Cheyenne.

The railway, now owned by the Burlington Northern, was abandoned and torn up by 1983, leaving Stoneham without any rail access.
