Lya IV was the fourth planet in the Lya planetary system. This system was located within Sector 30. In the mid-2360s, a Federation outpost was located on this planet.

In 2366, the freighter Jovis, commanded by Kivas Fajo, spent more than half a day in orbit of this planet. While at this planet, Fajo entertained his friend Palor Toff. The outpost would later send a message to the USS Enterprise that Kivas Fajo's ship had been seen at the planet.(TNG: "The Most Toys")
