Antros III was a planet located in the galaxy's Alpha Quadrant, the third planet in orbit of the Antros star system. Antros III is situated in the space of the Cardassian Union, just beyond the Rolor Nebula.

Antros III was once a class M planet, but lost its atmosphere long ago. The moon of Antros III is habitable, despite near constant blizzard conditions. (SCE - What's Past eBook: Echoes of Coventry)
