Beta IV was a planet, the fourth planet of the Beta system, located in the Alpha or Beta Quadrants of the galaxy, in Federation space.

In 2264, the Vulcans erected a shrine on Beta IV to house the emotions their ancestors bottled thousands of years ago. The USS Enterprise was assigned to deliver them there, but never made it as the emotions were absorbed by Malok on Pollux II. (TOS comic: "The Brain Shockers")
