The USS Agamemnon (NCC-11638) was an Apollo-class Federation starship in service during the 23rd and 24th centuries.
In 2369, the Agamemnon took part in a Starfleet task force assigned to protect the Federation from a possible second Borg invasion. The invasion never came to fruition. (TNG: "Descent")
Sometime prior to, or on, Stardate 53441.4, the Agamemnon was under Commander Henry Grayum's command, serving within Starfleet's Border Patrol division. During this time, the Agamemnon crew undertook a reconnaissance mission responsible for bringing down a rogue Breen element which departed from the Treaty of Bajor. Following that mission, on Stardate 54338.5, Grayum retired as a captain, and command of the Agamemnon fell to Commander Richard D. James.

Agamemnon was reassigned to patrol the new treaty zone between the Federation and the Cardassian Union in late 2375. (Star Trek: The Quarterdeck Breed: "The Sacrifice of Agamemnon")
