Atomic Knight is a DC Comics superhero and was briefly a member of the Outsiders team. He is sometimes depicted as one of a group of Atomic Knights, which first appeared in Strange Adventures #117 (June 1960).

The Atomic Knights appeared in every third issue of Strange Adventures in the early 1960s, beginning with #117 (June 1960). Created by John Broome and Murphy Anderson, they were a band of heroes living in the post-apocalyptic future of 1992.

Following the catastrophic Hydrogen War of 1986, a petty tyrant named the Black Baron ruled a small section of the Midwest with an iron fist. He was opposed by Sgt. Gardner Grayle and the Atomic Knights, who wore medieval suits of armor that were impervious to the Baron's energy weapons, having been irradiated in the war. The other Knights were twins Wayne and Hollis Hobard, Bryndon Smith, the last scientist left on Earth, and brother and sister Douglas and Marene Herald.

The fifteen Atomic Knights stories in Strange Adventures took place in 'real time' (three months usually passed between the events of each story as well as in the real world) and generally dealt with post-holocaust recovery, as the Knights would fend off menaces and attempt to rebuild the area around their homebase of Durvale, though they also managed to travel to Los Angeles, Detroit, New Orleans, New York, and Washington, D.C. In all, there were fifteen early-1960s Atomic Knights stories; their last appearance in Strange Adventures came in issue #160 (January 1964).
