Gandakasia is an extinct genus of ambulocetid from Pakistan , that lived in the Eocene epoch. It probably caught its prey near rivers or streams.

Just like Himalayacetus, Gandakasia is only known from a single jaw fragment, making comparisons to other ambulocetids difficult.[3]

The first ambulocetid to be described, Gandakasia was not initially recognized as a cetacean.[4]

Gandakasia probably inhabited a freshwater niche similar to the pakicetids.[3]
