A regimental combat team (RCT) is a provisional major infantry unit which has seen use by branches of the United States Armed Forces. It is formed by augmenting a regular infantry regiment with smaller combat, combat support and combat service support units.

The United States Army first adopted the RCT concept just prior to World War II, where it served as the infantry-centric counterpart to the Combat Command used by armored forces. RCTs were widely used during World War II and the Korean War but were disbanded after the adoption of the Pentomic structure in 1957.

The United States Marine Corps maintains the use of the RCT to the present day.
