Magnez (Mg, łac. magnesium) – pierwiastek chemiczny, metal ziem alkalicznych (druga grupa główna układu okresowego). Ma trzy stabilne izotopy: 24Mg, 25Mg oraz 26Mg. Magnez po raz pierwszy został uznany za pierwiastek przez Josepha Blacka (1755), zaś wyodrębniony w formie czystej w 1808 roku przez Humphry’ego Davy’ego, który nadał mu łacińską nazwę. Polską nazwę zaproponował Filip Neriusz Walter.
