Alpha Quadrant

The Alpha Quadrant is a ficticious region of space featured in the Star Trek multimedia franchise. It represents one quarter of the Milky Way Galaxy and is the primary setting for most films, TV shows, books, comics and video games set within the Star Trek universe; the one exception being the Star Trek: Voyager television series, which takes place primarily in the Delta Quadrant. There are several major intergalactic governing bodies that exist within the Alpha Quadrant, most notably the United Federation of Planets. Others include the Klingon Empire, the Romulan Empire, the Ferengi Alliance and the Cardassian Union.

Other quadrants explored in Star Trek include the Gamma Quadrant, which is generally referred to as Dominion Space, the Delta Quadrant, which is home to the Borg, Species 8472, the Ocampa, the Talaxians and the Kazon, and the Beta Quadrant, which is home to the Yattho species.
