The Lambda Serpentis System is a star system in the constellation Serpens. It is 38.3 light years from the Sol System and was formerly a part of the UNSC's outer colonies. At least one planet in the system was colonized by humans at one time: the planet Jericho VII.

In 2535, the Covenant invaded the system and attacked the UNSC colony on Jericho VII. Even though the UNSC sent Spartans to help defend Jericho VII, the human defenses were overwhelmed and the Covenant began glassing the planet.

In 2552, a Fleet of Covenant ships was ordered to go to the Lambda Serpentis system to collect Tritium gas for their reactors in preparation to rendezvous with the Unyielding Hierophant and mass Slipspace jump to Earth, indicating that the system is now home to a Covenant refueling station at the very least. As such, it is one of few UNSC systems not entirely glassed and actually inhabited by the Covenant.
