Panthera tigris trinilensis, known as the Trinil tiger, is an extinct tiger subspecies dating from about 1.2 million years ago that was found at the locality of Trinil, Java, Indonesia.

[1] The fossil remains are now stored in the Dubois Collection of the National Museum of Natural History in Leiden, the Netherlands.

[2] It lived in Indonesia, particularly in Java and Trinil, and according to some zoologists, it could be the ancestor of all known Indonesian subspecies.

However, the glacial and interglacial climatic variations and other geological events may have caused repeated geographic changes in the area.

[2] Food competition among large carnivores is a major incentive to increase body weight, so that this Pleistocene subspecies's weight was slightly less than today's Bengal tigers and weighed about 110–150 kg (240–330 lb).
