Sector 30 was a region of space. This sector contained the Romulan Neutral Zone. Nine Federation outposts were established along the edge of the zone.

In 2364, two Federation outposts, Science Station Delta-05 and Tarod IX, were confirmed to have been destroyed by a then unknown enemy. (TNG: "The Neutral Zone") Less than a year later, in 2365, it was determined that the enemy was the Borg. (TNG: "Q Who")

In 2366, Admiral Haden sent a warning to this sector's outposts during the Nelvana III incident. (TNG: "The Defector")

Later that year, trader Kivas Fajo sabotaged the water supply on the Federation planet Beta Agni II. He would be later tried in a Federation court for this act of vandalism. (TNG: "The Most Toys")


In an okudagram from "The Most Toys", a line read: "Sector 30-439".
According to Star Trek: Star Charts (p. 66), Sector 30, also known as the Tarod sector, was located in the Beta Quadrant.
