Norcadia Prime was the main planet of the Norcadia planetary system. This system was located in the Delta Quadrant, and was the homeworld of the Norcadians.
Norcadia Prime was noted for its beautiful beaches and some of the finest museums in the sector. Among these museums was the Norcadian Museum of Entomology, which in 2376 had a special exhibit on beetle larvae from the equatorial subcontinent.
The USS Voyager visited Norcadia Prime in 2376. (VOY: "Tsunkatse")
In VOY: "Collective", Mezoti, described her homeworld as a Theta-class planetoid in a binary star system, with a population of 260 million. However, it was never made clear if this was Norcadia Prime or a colony.
