Alpha Centauri II is a Class M planet in the trinary Alpha Centauri system. It was colonized by Earth in the late 2060s, and is often referred to as the Alpha Centauri colony. The planet is a member of the Alpha Centauri Concordium of Planets and the United Federation of Planets.

In November 2064, Zefram Cochrane became the first human to set foot on Centauri II, having traveled there aboard the SS Bonaventure. He found a breathable atmosphere and Earth-like conditions, though the planet was uninhabited. Cochrane and his team would eventually relocate to the planet, and continue their pioneering work in warp physics.
After four years, through the efforts of Cochrane and Micah Brack, Earth established self-sufficient farming community on Centauri B II, supporting a fully-equipped warp (then called "continuum-distortion") research facility. Within a decade, there would be 33 Earth colonies on 10 extrasolar class M worlds.
The Centaurii races embraced the presence of the human colony in their star system, and trade was quickly established. Commercial space lanes were opened between Centauri, Earth and Vulcan in 2070, and a year later, Centauri II joined the Concordium of Planets, strengthening ties between those worlds and Earth.
In 2078, Cochrane returned to Centauri II with Monica Burke, fleeing from the Optimum Movement. He eventually settled on the Lazy Eight Ranch near Micah Township and married Burke. The Cochrane Foundation would be founded on Centauri sometime later.
In April of 2119, Colonel Adrik Thorsen assassinated Monica Cochrane and bombed the Foundation. Zefram Cochrane disappeared in the aftermath, and many memorials were dedicated to his memory on Centauri B II.
