The Grant Corporation was a major, multifacted Earth-based inter-planetary corporation in the 22nd Century.

Unlike other human companies of the period, the Grant Corporation was eventually known at times to take a more ethical approach to its pursuit of studying and capitalizing on the study and acquisition of Xenomorphs.

The company was responsible for a number of scientific advances in Xenomorph-based technology and pharmecuticals, including the creation of acid-proof clothing for the handling of Aliens, and the synthetic drug Xeno-Zip, derived from Alien Queens' secretions of Royal Jelly.

Grant owned Grant Corporation Station 13, which was host to a Xenomorph infestation and later nuked from orbit by the United States Colonial Marine Corps.
