O antimônio (português brasileiro) ou antimónio (português europeu), também chamado estíbio, é um elemento químico de símbolo Sb de número atômico 51 (51 prótons e 51 elétrons) e de massa atómica igual a 121,75 u. À temperatura ambiente, o antimônio encontra-se no estado sólido. O símbolo Sb é uma abreviatura do seu nome na língua latina, Stibium, convencionalmente abreviado Sb. É um semimetal (metaloide) do grupo 15 (VA) da classificação periódica dos elementos. Apresenta quatro formas alotrópicas. Sua forma estável é um metal de coloração branca azulada. O antimônio negro e o amarelo são formas não metálicas instáveis. O antimônio é empregado principalmente em ligas metálicas e alguns de seus compostos para dar resistência contra o fogo, em pinturas, cerâmicas, esmaltes, vulcanização da borracha e fogos de artifício. Foi descoberto em 1450 por Thölde.
