寄生火山锥是指岩浆在主要火山信道外溢出积聚而成的圆锥形地貌，例如夏威夷群岛毛纳基火山上有超过100个寄生火山锥，而意大利埃特纳火山则有超过300个寄生火山锥。

A parasitic cone (also adventive cone or satellite cone) is the cone-shaped accumulation of volcanic material not part of the central vent of a volcano. It forms from eruptions from fractures on the flank of the volcano. These fractures occur because the flank of the volcano is unstable. Eventually, the fractures reach the magma chamber and generate eruptions called flank eruptions, which, in turn, produce a parasitic cone.
