犀貘（学名Heptodon）是已灭绝的沼貘科。牠们生存于始新世的北美洲。

犀貘约长1米，外观像现今的貘。从其头颅骨的形状估计牠们没有貘的长鼻，但可能有稍长的上唇。从其标本估计牠们重15.5公斤。

Heptodon is an extinct genus of tapir-type herbivore of the family Helaletidae endemic to North America during the Eocene epoch. It lived from 55.4—48.6 mya, existing for approximately 6.8 million years.
