Ang sodyo (Ingles: sodium; Espanyol: sodio) ay isang elementong kimikal sa talahanayang peryodiko na sinasagisag ng simbolong Na, hango sa Latin na natrium, at nagtataglay ng atomikong bilang 11.

May atomikong bigat 22.99, punto ng pagkatunaw na 97.8 °C, punto ng pagkulong 892 °C, espesipikong grabidad na 0.971, at V na 1) ay isang elementong metalikong sumasabog kapag hinaluan ng tubig. Kabilang sa katangiang pisikal nito ang pagiging malambok, parang pilak, at napupupukpok. Nagiging asin ito kapag sumanib na sa klorido. Nagagamit ito sa paglikha ng maraming mahahalagang mga kompawnd o kumpuwesto. Natuklasan ito noong 1807 ni Humphry Davy.^[8]
