Medjel is a fictional race of lizard-like beings in the Culture universe created by Iain Banks.

The medjel originally evolved in a social symbiosis with the Idirans, who then bred them as a companion species over the course of forty thousand years (by the time of the Idiran-Culture War). They are reckoned to be about two thirds as intelligent as the average humanoid and outnumber the Idirans by about 12 to 1, making them good, if unimaginative, soldiers.

Physically, the medjel are about two metres long, with green-brown skin. They have flat, long heads with distinct muzzles, walk on four feet and use two front feet as hands. The tail of military medjel is docked.
