棘皮动物门(學名:Echinodermata)是动物界的一门。这个门从寒武纪出现,总共有20000多种类,现生种约5000余种。除现生5纲外,另有15纲之多,皆為海生動物,無陸生或淡水種類。常見的海膽、海參與海星皆屬於此門。 棘皮动物是后口动物。牠们的原肠胚孔形成肛门,而口部是后来形成的。牠们有特殊的五体对称步管结构。棘皮动物的次生体腔发达,是由腸體腔(enterocoele)发育形成。 由於棘皮动物在胚胎形成方式及DNA序列上與脊索动物相似,被認為是包括人在内的脊索动物的近亲。 棘皮动物特有的结构是水管系統(英语:water vascular system)和管足(英语:Tube foot),用於移動、攝食及呼吸,也是一種感覺器官。 刚出生的棘皮动物是两边對稱的。成长期间,左边增大而右邊縮小,直到右边被完全吸收了,然后这一边长成五倍辐形对称形状。
