The Billings Depot is a historic building in Billings, Montana. It was originally a train depot constructed to function as a passenger station for the Northern Pacific Railroad, Chicago, Burlington and Quincy and the Great Northern.
Completed in 1909, the Billings Depot is said to have played a major role in the local railroad history and development of the city. It was designed in the Beaux Arts Eclectic style and is composed of four structures, including the office, mail, depot buildings and the railroad lunch room. In 1979, the site saw its last Amtrack Passenger Train leave its depot.

The Billings Depot was recently restored and renovated. It is now open as an events venue available for rentals and such.
