Orb was a science fiction fanzine by Bob Johnson and Charles Hames.
Orb was published in the early 1950s in Greeley, Colorado, U.S.A. In the ad for Orb printed in Wastebasket, it called itself "the avant garde fanzine".
Joe Green wrote in the first issue of Confusion, "ORB was the fines fanzine these palsied palms have ever clasped..."
In his November 1952 "Clubhouse" column for Amazing Stories, Rog Phillips mentions that featured in the latest Orb was a three way collaborative story from Fritz Leiber, Judith Merril, and Frederic Brown.
Artists featured included Hannes Bok.
