Ishatherium is an extinct genus of ungulate from the early Eocene of the Subathu formation in northwestern India. It is only known from a partial upper molar and was formerly classified as a sirenian. It was placed in Anthracobunidae in 1983 but this placement was rejected in a 2014 cladistic analysis.
