The inaugural season of the action comedy science fiction machinima web series Red vs. Blue premiered on April 1, 2003 on Rooster Teeth's official website. The season consists of 19 episodes, and concluded on September 28, 2003. The series is loosely based in the Halo universe, and is created by Rooster Teeth Productions.

The series follows the accounts of the Red Team which consists of: The leader, Sarge; the lazy one, Grif; the "kiss ass", Simmons; the semi-idiotic Donut; and the Spanish robot Lopez. The series also follows the accounts of the Blue Team, which consists of their De facto leader, Church; the self-proclaimed ladies' man, Tucker; and the clueless Caboose. The Freelancer Tex is often associated with the Blue Team. Season one regular characters include Sarge, Simmons, Grif, Donut, Lopez, Church, Tucker, Caboose, Tex, Sheila, and Vic.

The episodes were filmed primarily using machinima techniques, and Halo: Combat Evolved. Episodes were written by members of the Rooster Teeth crew. Episodes aired weekly, and were posted on the Red vs Blue website.
