'ancient Panthera') is an extinct genus of pantherine felid which lived during the Late Miocene to Early Pliocene of Asia.

Known from a partial skull and isolated teeth, the fossils of P. blytheae were first excavated in August 2010 in the Zanda Basin located in the Ngari Prefecture on the Tibetan Plateau, and were subsequently described and named in 2014.

[1] While P. blytheae was initially suggested to be related to the modern snow leopard,[1] various researchers since 2017 have questioned the classification of the poorly preserved P. blytheae to the genus Panthera based on limited comparisons to other species including the snow leopard, and as lacking features that comply with Panthera features.

[3] In the same year, the describers of Pachypanthera recognized Hemmer's new genus Palaeopanthera but didn't comment on its generic validity.

This implies that the divergence of Panthera from the rest of Felidae was much earlier, with current estimates being approximately 16.4 million years ago.
