Bant's Carn is a Bronze Age entrance grave located on a steep slope on the island of St Mary's in the Isles of Scilly, England.

Bant's Carn is situated on a steep slope on the island of St Mary's in the Isles of Scilly.

Burials on the islands range in date from the later Neolithic period to the Middle Bronze Age (2500-1000 BC).

Bonsor found the tomb empty except for cremated human remains at the back of the chamber, along with sherds of Neolithic and Bronze Age pottery.

Later restoration work in 1970, led by P. Ashbee, included re-setting the tomb's eastern capstone and southern portal stone.
