Youngstown and Austintown Railroad (reporting mark YARR) is a short-line railroad that operates just west of Youngstown, Ohio, United States, and was acquired by Genesee & Wyoming Inc. in 2008.

Acquired by Genesee & Wyoming in 2008, the Youngstown and Austintown Railroad spans across 5 miles of track and can hold up to 286,000 pounds of supplies.

For years the largest customer on the YARR was Youngstown Steel Door and United Freezer Storage.

The one-stall enginehouse still stands today in Austintown on Oakwood Ave. A small section of the structure was constructed by the Erie railroad.

The bridge over the Mahoning River, which connected the sections from the ex-Erie mainline to the Baltimore & Ohio Railroad at YANDA has been demolished and shows no signs of reconstruction.
