Kriemhild (minor planet designation: 242 Kriemhild) is a main belt asteroid that was discovered by Austrian astronomer Johann Palisa on 22 September 1884 in Vienna[2] and was named after Kriemhild, a mythological Germanic princess, by Moriz von Kuffner, a Viennese industrialist and sponsor of astronomy.
