蠍子（學名：Scorpiones）是一種有8隻腳的掠食性蛛形綱節肢動物，具有一對可固定獵物的鉗足與細長且分節的尾，尾部末端為帶有毒液的蜇針（英语：stinger）。蠍子的體長約在9 mm（0.35英寸）（Typhlochactas mitchelli（英语：Typhlochactas mitchelli））至23 cm（9.1英寸）（紅爪雨林蠍）之間。最早的蠍子出現於4億3千萬年前的志留紀，在南極洲以外的所有大陸均有分布，目前現存在蠍目底下有13科共約1750種。所有的蠍子都具有毒針，但大部分的物種均不對人類造成威脅，甚至在被叮後不需要接受任何醫療支援。目前已知僅有25種蠍子的毒液會對人類生命造成威脅。
