Terraform Command was an agency of the United Federation of Planets that was responsible for the coordination and implementation of the terraforming of celestial bodies.

In 2364, Terraform Command dispatched the USS Enterprise-D to the planet Velara III, in order to investigate the erratic communications coming from the Velara Base there, and the subsequent concern that was raised about the welfare of the base's personnel. (TNG: "Home Soil")

A year later, the USS Constantinople was on special assignment for this agency. (TNG: "The Measure Of A Man", display graphic)
