"Samburupithecus" was a primate that lived in Kenya during the middle to late Miocene. The one species in this genus, "Samburupithecus kiptalami", is known only from a maxilla fragment dated to 9.5 Ma discovered by Hidemi Ishida and Martin Pickford in 1997. "Samburupithecus" was approximately 60 kg and was most likely a frugivorus terrestrial quadruped (Fleagle, 1999). Paleoenvironmental reconstructions indicate that "Samburupithecus" most likely lived in a wooded habitat surrounded by savannah (Tsujikawa, 2005).

Defining cranial traits of this genus include low, broad zygomatics, straight alveolar process and large maxillary sinus. Defining dental traits include three-rooted premolars, thick enamel and buonodont cusps (Ward, 2002). Unlike many other Miocene hominoids, "Samburupithecus" has teeth that are elongated from front to back. This feature links the taxon to gorillas, chimpanzees and hominins, but its relationships within this clade are presently unknown (Fleagle, 1999).
