Konrad von Altstetten (fl. 1320–1327) was a German petty nobleman and Middle High German lyric poet in the Minnesang (courtly love) tradition. He belonged to a family of vassals of the Abbey of Saint Gall, based in Altstätten. His poetry, light in style, was influenced by Gottfried von Neifen. Three of his songs are preserved in the Codex Manesse.
