Sigismund (variants: Sigmund, ) is a German proper name, meaning "protection through victory", from Old High German "sigu" "victory" + "munt" "hand, protection".
 Tacitus Latinises it "Segimundus".
 There appears to be an older form of the High German word "Sieg" (victory): "sigis", obviously Gothic and an inferred Germanic form, and there is a younger form: "sigi", which is Old Saxon or Old High German "sigu" (both from about 9th century).
 A 5th century Prince of Burgundy was known both as "Sigismund" and "Sigimund" (see Ernst Förstemann, "Altdeutsche Personennamen", 1906; Henning Kaufmann, "Altdeutsche Personennamen", Ergänzungsband,1968).
