Moropus (meaning "slow foot") is an extinct genus of perissodactyl ("odd-toed") mammal that belonged to the group called chalicotheres, which were endemic to North America during the Miocene from ~23.0--13.6 Mya, existing for approximately 9.4 million years.
Moropus is related to the modern horse, rhino, and tapir.
