The choices we made on Voyager changed this quadrant, and not all of those changes were positive. We did what we needed to do to get home. Now, we must do what we must to heal the wounds we left behind. - Seven of Nine

The Delta Quadrant is one of four quadrants in the Milky Way Galaxy. It is where the starship U.S.S. Voyager spent seven years (2371-2378) before returning to Federation territory. They made first contact with numerous species, including the Undine and the Voth, which are not native to the quadrant. In 2410, the Delta Alliance formed by Federation, Klingon and Romulan forces, returned to the Delta Quadrant by using Iconian gateways.

This article is about the quadrant. For the similarly named mission chain, see The Delta Quadrant.

The Delta Quadrant consists of six sectors (covering the path Voyager took) and the Solanae Dyson Sphere, which is ca. 30.000 lightyears from the Sol System, close to Beta Quadrant border, and was accessible before Delta Rising was released. Note that the sector size in the Delta Quadrant is not identical to those in the Alpha and Beta Quadrants.
