The Raid on San Francisco was a sneak attack by the forces of the Breen Confederacy in late 2375 during the Dominion War. Although most attacking Breen ships were destroyed by Starfleet defenses, the Breen managed to cause massive damage to Starfleet Headquarters, the city of San Francisco, and the Golden Gate Bridge.

This attack was a further blow to Federation morale and boldly announced the Breen Confederacy as an ally of the Dominion. An attack of this magnitude had not occurred on Earth in 200 years and as General Martok stated "not even we managed to do that."

The damage caused by this attack was fully repaired by 2376.
