The Boulder Railroad Depot is a retired train depot in Boulder, Colorado. It was originally built in 1890 in downtown Boulder to serve as a depot for the Union Pacific railroad. The depot was built in a modified Richardson Romanesque style from native Boulder County stone. The depot operated as a train station at its original location until 1957, when a new depot opened and replaced it. In October 2008, the City of Boulder and the Colorado Regional Transportation District moved the depot again, this time to the site of a new, transit-oriented development a few city blocks to the east.
