The 182nd Infantry Regiment is a regiment of the United States Army, forming part of the Massachusetts National Guard. It is the oldest regiment in the U.S. Army, sharing its lineage with the 181st Infantry and tracing its organizational roots back to 1636. It is one of several National Guard units with colonial roots and a campaign credit for the War of 1812.

The 182nd Infantry traces its history back more than 230 years, when it was part of the Massachusetts colonial militia. It later served in the Continental Army during the American Revolutionary War, with Union forces in the American Civil War, and as a federalized Massachusetts National Guard regiment with the U.S. Army during World War I and World War II.

For many years, the 182nd Infantry was a mechanized infantry unit. In 2006, it converted into the 182nd Cavalry Regiment, headquartered at Melrose Armory in Melrose, Massachusetts. It was converted back into an infantry regiment in 2010. The only currently active element of the regiment is its 1st Battalion.
