The Mariposa colony was an Earth colony located on the class M planet Mariposa, located in the Ficus sector. The colony was established in the mid-22nd century from the remains of the colony ship SS Mariposa, the colony's namesake. This colony was the sister colony of the Bringloid V colony.

Although originally intended to be established by a group of technology-savvy scientists, this all changed when the Mariposa began its planetary descent. As the ship attempted to land, the hull of the ship was breached and only five of the original colonists survived. Over time, however, they were able to build a large complex containing their medical facility, including a cloning lab, living quarters, and offices.

Due to the status of Earth's government in the early 22nd century, the SS Mariposa, the Mariposa colony and Bringloid V colony were forgotten and there were no attempts made at communication.

In 2365, the USS Enterprise-D visited the colony when it learned of its existence from the Bringloidi, having followed their SOS which was picked up by Starbase 73.

When the Enterprise crew learned of the fact that the Mariposans were clones suffering from replicative fading, Jean-Luc Picard recommended that the Bringloidi, who were otherwise homeless, resettle to the Mariposa colony to solve both of their problems. The colony then expanded to include them, their animals and equipment. (TNG: "Up The Long Ladder")
