Siamogale is an extinct genus of giant otter from the late Miocene of Asia. Two species are currently known.

The skull reveals a combination of otter-like and badger-like cranial and dental characteristics. The new species belongs to the Lutrinae because of its possession of a large infraorbital canal and ventral expansion of the mastoid process, among other traits. Siamogale melilutra was about the size of a wolf and weighed as much as 50 kg (more than 100 pounds). This is two to three times larger than any modern otter species. The remains of the skull were found in China and were re-created with a special program called the CT scan which is able to reconstruct the skeleton without being damaged.
