The United States Taiwan Defense Command (USTDC; Chinese: 美軍協防台灣司令部; pinyin: Měijūn Xié Fáng Táiwān Sīlìng Bù) was a sub-unified command of the United States armed forces. It was originally formed as the Formosa Liaison Center (founded in 1955 after the signature of the US-Taiwan Mutual Defense Pact of December 1954 and the first Straits crisis of Sept. 1954). In November 1955, the FLC become the Taiwan Defense Command. The command reported directly to the Commander-in-Chief Pacific (CINCPAC). The command was composed of personnel from all branches of the U.S. armed forces and had its headquarters in Taipei. The first commander of the USTDC was Alfred M. Pride (command of the U.S. Seventh Fleet).

USTDC was a planning headquarters for the defense of Taiwan and the Pescadores. In the event of hostilities, the USTDC commander would have coordinated with the Government of the Republic of China in the defense of Taiwan and the Pescadores. In the event of such a contingency, three existing service commanders would have reported to the U.S. Taiwan Defense Command commander. The 327th Air Division commander would be the air component commander, the Taiwan Patrol Force commander would be the naval component commander (the Taiwan Patrol Force being drawn from the United States Seventh Fleet), and the Chief of the Military Assistance Advisory Group (MAAG) would be the Army component commander. The 3rd Tactical Fighter Wing, Thirteenth Air Force, at Clark Air Base in the Philippines had reinforcement air defence functions for Taiwan for a period.
