The Weston County Courthouse in Newcastle, Wyoming, was designed by Charles A. Randall and built in 1910–11.

The Beaux-Arts style courthouse is the most elaborate building in Newcastle, and a symbol of the community's prosperity at the time of its construction.

The parapet is ornamented by galvanized metal globes with astatue of Justice on the top of the pediment.

Work was complete in 1911, in time for a visit in October and an address from the courthouse steps by U.S. President William Howard Taft.

The addition uses sandstone for the first two stories and brick for the upper floor to match the main building.
