Angmagnesyo (Ingles:magnesium) ay isangelementong kimikal satalahanayang peryodiko na sinasagisag ng simbolongMg at nagtataglay ngatomikong bilang12.

May atomikong timbang na 24.312, punto ng pagkatunaw na 651 °C, punto ng pagkulong 1,107 °C, espesipikong grabidad na 1.74, atV na 2) ay isang elementong metalikong may katangian ng pagiging magaan, parangpilak, at medyo may katigasan lamang. Kapag nasa anyong pulbos o kayalaso oribon, nagsasanhi ito ng maputi at maliwanag na liwanag kung nasusunog o kapag sumasabog. Nagagamit ito sa paggawa ng mgapailaw (mgapirotekniko oluses,aloy,pasiklab oflash sa Ingles ngkamera, at mgabomba. Natuklasan ito niHumphry Davy noong 1808.[13]
