La tefroíta es un mineral de la clase de los nesosilicatos, y dentro de esta pertenece al llamado “grupo del olivino”. Fue descubierta en 1823 en una mina de Franklin, en el estado de Nueva Jersey (EE. UU.), siendo nombrada así del griego tephros -ceniza-, en alusión a su color. Un sinónimo poco usados es: peridoto-mangánico.
