Gorik IV was a planet in Federation space.

In 2371, shortly after the destruction of the Amargosa star, a research project on Gorik IV was halted due to increased neutrino particles. Commander Data noted this, along with other effects, in a report to Captain Jean-Luc Picard in Stellar Cartography aboard the Enterprise-D during the investigation into the actions of Tolian Soran. (TNG novelization: Generations)

Gorik IV is referenced in both the novelization and shooting script of the film, but the line itself does not appear in the movie.
