The Alexander romance is any of several collections of legends concerning the mythical exploits of Alexander the Great. The earliest version is in Greek, dating to the 3rd century. Several late manuscripts attribute the work to Alexander's court historian Callisthenes, but the historical figure died before Alexander and could not have written a full account of his life. The unknown author is still sometimes called Pseudo-Callisthenes.

The text was recast into various versions between the 4th and the 16th centuries CE, in Medieval Greek, Latin, Armenian, Syriac, Hebrew and most medieval European vernaculars.
