Ajilon Prime was the inhabited prime planet in the Ajilon system. This system was located near the Federation-Klingon border in the Beta Quadrant. In the 24th century, this planet was home to a Federation colony with several settlements. The colonial government was partially administrated by Resource. The planet was located "three days at best" from Deep Space 9.

In early 2373, the planet was attacked by the Klingons during the Federation-Klingon War, breaking the cease fire that was initiated a few weeks earlier. In the ensuing Battle of Ajilon Prime, the Klingon forces were quickly able to capture two settlements in the northern hemisphere, trap over half the colonists on the planet and then advance further. During the battle, colonists were evacuated to a base on Tananda Bay by Resource.

Reinforcements were dispatched aboard the USS Farragut, but the vessel was destroyed before reaching the planet. The USS Defiant reached the planet two days later, and Klingon forces pulled out following the reinstatement of the ceasefire. (DS9: "Nor the Battle to the Strong")
