Artifact land is a term used in reference to the six common land cards printed in Mirrodin and Darksteel that also have the artifact type. They contributed to the dominance of the affinity-based deck archetypes, and thus, in March 2005, all six were banned from Standard (Darksteel Citadel however, was later reprinted in Magic 2015), and the ban did not carry over with the reprint. In Modern format, all but Darksteel Citadel were banned from the beginning. Additionally, the location depicted in each was featured in the art of the appropriate Sun's Zenith card from Scars of Mirrodin.

- The artwork of each colored artifact land was picked up to by a respective basic land from New Phyrexia, representing darker versions of the original.
