A Federation star chart depicting the location of Berengaria VII
The Berengarius system was an important Federation planetary system around the star Berengaria in the Alpha Quadrant. In the 24th century, it held a similar importance and significance as other core Federation planets, such as Vulcan, Andor, and perhaps even Earth. (DS9: "In the Cards")

The Berengarius system contained a Class M world, Berengaria VII, which was first explored by a Vulcan survey team in the early 2100s.
In December of 2154, Enterprise NX-01 was assigned to the Berengaria system to scout for suitable planets on which the first of a series of proposed starbases could be built. Berengaria VII was a potential candidate. (ENT: "Bound")
