拟蝎目（学名：Pseudoscorpionida），又名书蝎目，是一些小型种类，体长多小于8mm，稀有达到厘米的，所以平时甚少被察觉。其体型似蝎，故名。但它们腹部几近等宽，而无腹部和后腹部之分，也无蛰器。拟蝎类广泛分布于朽叶、土壤、树皮下石下或苔藓植物中，有些种在沿海潮间带的漂浮物或海藻上。由于它们个体太小，又加栖息地性质等原因而很少被人注意。实际上它们广泛存在，而且种类丰富，已知有2000余种，在某些地区密度很大。

拟蝎目生物一般对人类无害，因为他们依靠衣蛾、蚂蚁等各种害虫的幼虫作食粮。

A pseudoscorpion, also known as a false scorpion or book scorpion, is an arachnid belonging to the order Pseudoscorpiones, also known as Pseudoscorpionida or Chelonethida.

Pseudoscorpions are generally beneficial to humans since they prey on clothes moth larvae, carpet beetle larvae, booklice, ants, mites, and small flies. They are tiny and inoffensive, and are rarely seen due to their size.
