The United States Fleet Activities Yokosuka (横須賀海軍施設, Yokosuka kaigunshisetsu^?) or Commander Fleet Activities Yokosuka (司令官艦隊活動横須賀, Shirei-kan kantai katsudō Yokosuka^?) is a United States Navy base in Yokosuka, Japan. Its mission is to maintain and operate base facilities for the logistic, recreational, administrative support and service of the U.S. Naval Forces Japan, Seventh Fleet and other operating forces assigned in the Western Pacific. CFAY is the largest strategically important U.S. naval installation in the western Pacific. As of August 2013^[update], it was commanded by Captain David Glenister.

Fleet Activities Yokosuka comprises 2.3 km² (568 acres) and is located at the entrance of Tokyo Bay, 65 km (40 mi) south of Tokyo and approximately 30 km (20 mi) south of Yokohama on the Miura Peninsula in the Kantō region of the Pacific Coast in Central Honshū, Japan.

The 55 tenant commands which make up this installation support U.S. Navy Pacific operating forces, including principal afloat elements of the United States Seventh Fleet, including the only permanently forward-deployed aircraft carrier, USS Ronald Reagan (CVN-76), the group she heads, Carrier Strike Group Five, and Destroyer Squadron 15.
