The 105th Cavalry Regiment is a regiment in the United States Army National Guard.

The Regiment has been formed three times, and due to the complicated lineage system of the United States Army, all three formations are now considered as completely separate units. The first formation later became the 126th Field Artillery Regiment (United States). The second was initially formed as the 132nd Tank Battalion.
