鬣齿兽科（学名：Hyaenodontidae）是已灭绝的肉齿目下的一科，其下包含了几十属的动物。

鬣齿兽科于古新世晚期出现，并一直繁衍至中新世。^[1]牠们比相关的牛鬣兽科分布更为广泛及成功。^[2]牠们有长的头颅骨，幼长的身体，及倾向于跖行。牠们肩高约30-140厘米。^[2]当中的巨鬣齿兽可以重约500公斤，而大部分介乎于5-15公斤，如中等狗的大小。^[3]牠们的头颅骨化石显示牠们有敏锐的嗅觉，而牙齿亦很适合撕开食物，而非咬碎。^[2]

由于鬣齿兽科的不同体型，估计牠们会以不同的方式来捕猎。细小的可能是成群的在夜间猎食，较大的则可能是单独于日间猎食的。牠们的第二上及第三下臼齿是裂肉齿。

鬣齿兽科分布在北美洲至非洲^[4]^[5]，且是渐新世欧亚大陆、非洲及北美洲上非常重要的大型肉食动物，但后来不名食肉目而差不多在渐新世末完全消失。其中只有四个属，包括伟鬣兽属、Hyainailouros、Dissopsalis及鬣齿兽属下的Hyaenodon weilini，生存至中新世，而当中只有Dissopsalis可以延续至中新世末期。
