Ignacy — imię męskie o niepewnej do końca etymologii. Według najbardziej rozpowszechnionej teorii wywodzi się je od łacińskiego wyrazu ignis, oznaczającego "ogień". Zachodzi jednak również podobieństwo między tym imieniem, a nazwą łacińskiego rodu Egnacjuszów (Egnatii). Istnieją też hipotezy o etruskim pochodzeniu Ignacego.
