The 105th Cavalry Regiment is a regiment in the United States Army National Guard.
A regiment with this designation has been formed three times, and due to the lineage system of the United States Army, all three formations are considered completely separate units. The first formation later became the 126th Field Artillery Regiment. The second was initially formed as the 132nd Tank Battalion.
