The 501st Aviation Regiment is an aviation regiment of the US Army. It draws its history from the original aviation battalion of the 1st Armored Division, the 501st Aviation Battalion.

Relieved from the 1st Armored Division, reorganized and re-designated 16 October 1988 as the 501st Aviation, a parent regiment under the United States Army Regimental System with headquarters in Korea. The regiment has undergone numerous changes and has served in numerous conflicts including Joint Endeavor (Bosnia/Herzegovina), Operation Iraqi Freedom (OIF III), Operation Spartan Shield (Kuwait), Operation Inherent Resolve (Iraq) and Operations Enduring Freedom and Freedoms Sentinel (2013 and 2019 respectively) in Afghanistan.
