StarCraft is a military science fiction media franchise created by Chris Metzen and James Phinney and owned by Blizzard Entertainment. The series, set in the beginning of the 26th century, centers on a galactic struggle for dominance among four species—the adaptable and mobile Terrans, the ever-evolving insectoid Zerg, the powerfully enigmatic Protoss, and the "god-like" Xel'Naga creator race—in a distant part of the Milky Way galaxy known as the Koprulu Sector.

The series debuted with the video game StarCraft in 1998. It has grown to include a number of other games as well as eight novelizations, two Amazing Stories articles, a board game, and other licensed merchandise such as collectible statues and toys.

On March 27, 2017, Blizzard announced StarCraft: Remastered, a remastered version of the original StarCraft, with the core updates being up-to-date graphics and revised dialogue and audio. As of April 19, 2017, the original StarCraft and its Brood War expansion are free to download and play from Blizzard's website.
