角鲨科（学名Squalidae）是角鲨目下的一科。这科鲨鱼都有圆滑的背鳍鳍棘，在上颚及下颚的牙齿大小接近，尾柄有两侧龙骨。牠们一般都有上尾前小窝，尾鳍没有近端凹刻。

The Squalidae, also called dogfish sharks or spiny dogfishes, are a family of sharks in the order Squaliformes. They have two dorsal fins, each with smooth spines, but no anal fin, and their skin is generally rough to the touch. Unlike virtually all other shark species, dogfish sharks possess venom which coats their dorsal spines – this venom is mildly toxic to humans.
