The USRA 0-8-0 was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I. This was the standard heavy switcher locomotive of the USRA types, and was of 0-8-0 wheel arrangement in the Whyte notation, or "D" in UIC classification.

A total of 175 locomotives were built under USRA control; these were sent to the following railroads:

After the dissolution of the USRA, an additional 1,200 copies of the USRA 0-8-0 were built for many railroads, There is a known survivor of this Type, Republic Steel Corp. #285, which is an ALCO (Richmond) product built in 1925. It is now preserved at the Kentucky Railway Museum in New Haven, Kentucky. It is unknown if any more USRA 0-8-0s of this type exist.
