Ang argon (Espanyol: argon, Ingles: argon, may sagisag na Ar, atomikong bilang na 18, atomikong timbang na 3.94, punto ng pagkatunaw na 189.4 °C, at punto ng pagkulong 185.9 °C) ay isang gas at elementong hindi kumikilos o hindi gumagalaw, walang amoy, at wala ring kulay. Sa pagtataya, ito ang bumubuo ng 1% ng atmospera ng daigdig. Natuklasan ito nina William Ramsay at John Strutt, Ikatlong Baron Rayleigh noong 1894. Isa itong sangkap sa loob ng mga may kuryenteng ilaw at ginagamit ding sangkap sa mga tubong pangradyo.^[9]
