Starfleet Headquarters is the complex of buildings located on Earth from which the Federation Starfleet is administrated by Starfleet Command. Headquarters' grounds encompasses territory adjacent to the City of San Francisco on either side of the Golden Gate Bridge. The term can also apply to one specific building in the complex from which central decisions are made. (DS9 novel: Hollow Men, DS9 episode: "Homefront".)
The Headquarters complex was originally built as the command center of the United Earth Starfleet in the early 22nd Century on what was previously a portion of Golden Gate National Recreation Area in Marin County, overlooking Horseshoe Bay. After the founding of the United Federation of Planets in 2161, the site was used for the Federation Starfleet. By the 2270s, the headquarters expanded to the Presidio, an ancient military post on the southern side of the Golden Gate where it included an air tram station. (TOS novel Traitor Winds; TOS film: Star Trek: The Motion Picture)
In 2286, Federation President Hiram Roth attempted to coordinate disaster relief from Starfleet Headquarters as the Cetacean Probe inadvertently caused extensive damage to Earth's infrastructure and environment during its search for the extinct humpback whale species. It was from Starfleet Headquarters that the President issued a planetary distress call, warning all ships away from Earth. (Star Trek IV: The Voyage Home.) Janice Rand, a former officer on the USS Enterprise served as a communications officer at Headquarters that year while she cared for Demora Sulu, the teenaged daughter of Hikaru Sulu. (TOS novel: The Captain's Daughter).
In 2293, a memorial service for James T. Kirk was scheduled to take place at Headquarters, but when news was received at the sheer number of mourners that would attend the service, it was moved to the grounds of Starfleet Academy. (TOS novel: Crucible: The Fire and the Rose).
In 2364, Starfleet Headquarters was infiltrated by the Parasites, who seized control of many of Starfleet Command's high-ranking admirals until Captain Jean-Luc Picard and Commander William T. Riker of Earth exposed the conspiracy and killed the parasite spawnmother. (TNG episode: "Conspiracy".)
In 2372, Admiral James Leyton replaced many key officers at Starfleet Headquarters with those loyal to him as part of his attempted military coup. He planed on ruling the Federation from Headquarters; unfortunately for him, his plans were exposed, and he turned himself in to Starfleet Security in Headquarters to be court-martialed. (DS9 episode: "Paradise Lost".)
In 2374, the grounds of Starfleet Headquarters were the site of an anti-war peace rally at which the keynote speaker was Tomas Roeder attended by Federatoin Starfleet Captain Benjamin Sisko and Cardassian exile Elim Garak. Unfortunately, the rally became violent due to the presence of political extremists within the crowds. That same week, Headquarters hosted a conference of leaders from the Federation Starfleet, Klingon Defense Force, Romulan Imperial Fleet, and Cardassian government-in-exile in order to coordinate upcoming battle campaigns. (Hollow Men.)
In late 2375, during the Dominion War, Starfleet Headquarters was attacked by the Breen Confederacy. Buildings were badly damaged, including the historic Golden Gate Bridge, and many people were killed. (DS9 episode: "The Changing Face of Evil".)
