闭眼亚目（学名：Myopsina），俗称锁管，是一种外貌跟鱿鱼很相像的生物，属于软体动物门头足纲鞘亚纲十腕总目管鱿目。

闭眼亚目可以分为以下两个科：

• Family Australiteuthidae
• 枪乌贼科（或称「枪测科」，Loliginidae）：透抽、小管、软丝仔，均属之。

另外，亦有部分分类把闭眼亚目提升成为闭眼目（Myopsida）。

Myopsina is a suborder of squid containing two families: the monotypic Australiteuthidae and the diverse and commercially important Loliginidae (~50 species). Some taxonomists raise this group to the level of an order, in which case it is known as Myopsida. This is due to Myopsina and Oegopsina not being demonstrated to form a clade.
