The Norpin colony was a Federation retirement community on Norpin V.

In 2294, Captain Montgomery Scott was due to retire at the Norpin colony. However, his transport, the USS Jenolan, crashed on a Dyson sphere en route. Scott survived for seventy-five years by suspending himself in the Jenolan's transporter buffer, until he was rescued by the USS Enterprise-D in 2369.

Following his experiences with the crew of the Enterprise-D, Scott elected not to go to the Norpin colony, but rather to continue his voyages aboard an Enterprise shuttlecraft, Goddard. (TNG: "Relics")

This colony was only mentioned in dialogue.
In ultimately excised dialogue from the first draft script of "Relics", Montgomery Scott commented, "I hear the Norpin colony is very... quiet."
