肢口纲（学名：Merostomata）是一纲水生的螯肢亚门，其下包括了鲎。现存的肢口纲只剩一个剑尾目4个物种，分别为中华鲎、南方鲎、美洲鲎、圆尾鲎，但有大量主要属于古生代的化石物种。
肢口纲是螯肢亚门之中唯一拥有复眼的，而蛛形纲则失去了节肢动物祖先发展完好的侧前复眼。
史前的板足鲎纲（Eurypterida）曾被归类为本纲之下的一个亚纲，但后来被许多学者认为更接近蛛形纲，因而将板足鲎纲分出去独立成为一纲，与蛛形纲另组成硬器类（Sclerophorata）或Cryptopneustida。[1][2]
词源
[编辑]肢口纲的学名“Merostomata”是从希腊文 μηρός（meros，“大腿”）和στόμα（stoma，“口”）组合而来，因本纲动物的口器附近拥有附肢而得名。
