Starfleet Command, or Spacefleet Command, was the operating authority of Starfleet, the exploratory, scientific, and military department of the United Federation of Planets. The organization's primary management center was located at Starfleet Headquarters in San Francisco, Earth. (Star Trek IV: The Voyage Home) During the 22nd century and through the 23rd century, Starfleet Command was under the jurisdiction of the UESPA, notably during Captain James T. Kirk's era.

Starfleet Command is overseen by the Federation Council and run by a chief of staff, a position held by Admiral Jonathan Archer in the late-22nd century.

Besides the fleet, Starfleet Command also oversees the various other branches of Starfleet.

Because of the time delays involved in many subspace communications, Starfleet Command also includes a network of administrative and support outposts known as starbases throughout the Federation. Starfleet's starships operate out of these starbases under the supervision of various admirals, the senior officers of the fleet.

By 2364, Starfleet Command had been infiltrated by neural parasite aliens, who had physically taken control of the bodies of several high-ranking Starfleet officials, including Admiral Gregory Quinn, Admiral Aaron, and Admiral Savar. The parasitic mother creature resided in the body of Lt. Commander Dexter Remmick. The aliens were prevented from taking over Starfleet Command by Captain Jean-Luc Picard and Commander William Riker of the USS Enterprise-D, who, by destroying the mother creature, killed all alien parasites on the planet. (TNG: "Conspiracy")

In late 2373, Starfleet Command made a decision that would change the Federation forever. They agreed with Benjamin Sisko that no more Dominion ships could be allowed into the Alpha Quadrant. The mining of the Bajoran wormhole became the catalyst of the Dominion War. (DS9: "Call to Arms")

In 2374, Starfleet Command approved of Sisko's radical plan to bring the Romulan Star Empire into the Dominion War.

The order to quarantine a ship or station comes from Starfleet Command. (TNG: "Unnatural Selection")

The term "Starfleet" and "Starfleet Command" were first used in TOS: "Court Martial". Prior to this, in terms of air date, the term "Spacefleet Command" was used in "The Squire of Gothos".
