The Martinique giant ameiva (Ameiva major) was a species of lizard in the Teiidae family.It is believed to have been endemic to Martinique, though at least one scholar disputes this, instead placing it on Les Iles de la Petite Terre within the Guadeloupean archipelago. It is known only from museum specimens collected by early European explorers. Its extinction may have been caused by a hurricane, or through the introduction of predatory species to the island.
