Disestablished commands of the United States Navy

Disestablished commands of the United States Navy are major operational or administrative units which have since been disbanded or disestablished by the United States Navy. Disestablishing a command is slightly different from decommissioning an individual vessel, in that disestablishment normally refers to shore offices or high level fleet commands. Although, even in these contexts, the term "decommissioning" is frequently interchanged for these commands as well.

Flotillas were common in the 19th century American Navy but had largely disappeared by the early 1900s in favor of surface units known as "squadrons". One of the more famous flotillas was under the command of Matthew C. Perry who conducted several gunboat diplomacy visits to the Japanese islands in the late 1800s.

Naval squadrons have, in the modern U.S. Navy, become the primary administrative unit for naval ships, submarines, and aircraft. Historically, the U.S. Navy has maintained a number of squadrons which have since been disestablished.

In its history, the following fleets have been deactivated by the United States Navy

The term "Great White Fleet" referred to an early 20th century naval battle group which was formed from two battleship squadrons and completed a tour around the world under the orders of Theodore Roosevelt.

During World War II, the Fast Carrier Task Force (commonly known as "Task Force 38") was a battle group command designed to rapidly deploy to areas of the Pacific in order to engage the enemy. Several commands of the Second World War were also referred to as the "Western Naval Task Force".

In more recent times, a component of Commander Naval Forces Korea, previously known as "Commander Rear Area Naval Forces Korea" has since become known as Task Force 778, attached to the United States Seventh Fleet.
