Barbourofelis is an extinct genus of large, mostly carnivorous, mammals of the family Barbourofelidae (false saber-tooth cats). The genus was endemic to North America during the Miocene, living from 13.6—5.3 Ma and existing for approximately . 
Barbourofelis was named by Schultz and et al. (1970). Its type is Barbourofelis fricki and is the type genus of Barbourofelinae. It was assigned to Hoplophoneinae by Flynn and Galiano (1982); to Barbourofelinae by Bryant (1991); and to Nimravidae by Schultz and et al. (1970) and Martin (1998).
While Barbourofelis fricki is thought to have been lion-sized predator, other species in the genus, such as Barbourofelis morrisi are believed to have been closer to the size of leopards. Species in this genus had the longest canines of all the barbourofelids, which were also flattened, indicating a high degree of specialization to its diet. Other notable traits include the presence of a postorbital bar, the presence of a ventrally extended mental process (bony extensions on either side of the lower jaw), and the shortening of the skull behind the orbits.  It had a very robust constitution, with B. morrisi as intermediate between the size of Sansanosmilus and B. fricki, which is thought to have been a particularly large predator, the largest individuals of B. fricki being thought to have weighed up to 380 kg (829 lbs), with a reconstructed shoulder height of 95 cm (3 feet 11 inches).  The barbourofelids were probably very muscular, resembling a bear-like lion or lion-like bear.
