比利猿（英语：Bili Ape），又称邦多神秘猿（Bondo Mystery Ape），是一种生活在刚果民主共和国比利森林（Bili Forest）里的一种大型灵长类猿类动物或另一种传说生物。

“这种猿类像大猩猩一样生活在地面上，但是又具有类似黑猩猩的食谱和特征。”《国家地理杂志》的一位记者说。 用无核DNA做的初步基因测试表明，这种猿类和黑猩猩的Pan troglodytes schweinfurthii亚种关系很近。但是它们的行为和大猩猩又很像，这让世界各地的灵长类专家都十分好奇，因为这种猿类兼有黑猩猩和大猩猩的某些特点，人们对于这种猿类的分类仍有疑问及争议。

Bili ape, also Bondo mystery ape, is the name given to large chimpanzees that inhabit Bili Forest in the Democratic Republic of the Congo.

"The apes nest on the ground like gorillas, but they have a diet and features characteristic of chimpanzees", according to a National Geographic report. While preliminary genetic testing with non-nuclear DNA indicates a close relationship with the eastern chimpanzee (Pan troglodytes schweinfurthii) subspecies of the common chimpanzee, a range of behaviors that are more closely related to those of gorillas have greatly intrigued primatologists from around the globe. Though their taxonomic classification has been clarified, the need for further information about these chimpanzees persists.
