Leontoceryx is an extinct, little-known genus of pantherine felid. It was named in 1938 by Hungarian palaeontologist Miklós Kretzoi based on a partial upper jaw fossil with only three teeth present.^[1]

The holotype specimen was originally described in 1916 and assigned to Machairodus schlosseri by Alexejew,^[2] though Otto Zdansky in 1924 expressed doubt as to that identification based on Alexejew's illustration, which lacked the chin ridge seen in M. schlosseri and did have a groove on the canine tooth characteristic of felines.^[3]

A second specimen, a single lower canine tooth, was described by Kretzoi in 1951. It came from a locality near Csákvár, Hungary, and was dated back to the Late Miocene.^[4]
