A Reploid, also known as a Repliroid, is a type of robot found in the Mega Man (series) of video games. Reploids differ from less advanced robots such as Robot Masters because they are fully sentient, possessing true free will and the ability to learn and develop. Reploids that turn violent from glitches, computer viruses, or conscious decision are called Mavericks and regarded as highly dangerous. Combatants known as Maverick Hunters are tasked with catching or retiring Reploids who have "gone Maverick".

Reploids are often humanoid, but many are designed as anthropomorphic (or rarely, feral) animals.
