Morawanocetus is a genus of whale that is known to have lived in the waters around what is now Japan as well as California in the USA during the Oligocene. These discoveries indicate that Morawanocetus was widespread across the Pacific Ocean. As a member of the Aetiocetidae, Morawanocetus, would have been a relative of such genera as, Aetiocetus, Willungacetus, Chonecetus and Ashorocetus.
