Quercylurus major is an extinct, cat-like nimravid carnivora (or "false sabre-toothed cat") from the early Oligocene of France.

Q. major lived in the moist and humid forests of Oligocene Europe, alongside the much smaller, fellow nimravid Eofelis.

Quercylurus is often considered one of the largest definitive nimravids known, with remains indicating individuals roughly comparable to modern lions with mass estimates around 140 kilograms (309 lbs).

The canine fangs were large and scimitar shaped, if less elongated and flattened as derived Machairodontini sabretoothed cats and Barbourofelidae.

More recent research typically places Quercylurus, Dinailurictis, and Eofelis as closely related, but distinct genera representing a European clade of nimravids.
