Prototherium is a genus of extinct sirenian related to the dugong. It is known from middle (Bartonian) and upper Eocene deposits in Italy and Spain.[2]

Three species are now included in the genus, but their phylogenetic relations are not resolved and possibly one of them (Prototherium intermedium[3]) must be excluded. In the same way, relations between Prototherium and other genus are confused and need revision.
