快速航母特遣舰队（英语：Fast Carrier Task Force），有时亦称为第38特遣舰队（英语：Task Force 38）或第58特遣舰队（英语：Task Force 58）是美国海军在太平洋战争后期的主要战斗编制。一般由多个支队组成，每个支队通常编有三到四个航空母舰。参与了几乎所有太平洋战争后期美国海军的大规模战役。

该舰队具有第38特遣舰队和第58特遣舰队两个名字，主要是为了区分于该舰队的上级部队。当快速航母特遣舰队隶属于第三舰队的时候，使用TF 38的名义。当其隶属于第五舰队的时候，使用TF 58的名义。

The Fast Carrier Task Force was the main striking force of the United States Navy in the Pacific War from January 1944 through the end of the war in August 1945. The task force was made up of several separate task groups, each typically built around three to four aircraft carriers and their supporting vessels. The support vessels were screening destroyers, cruisers, and the newly built fast battleships.
