Ortrud (minor planet designation: 551 Ortrud) is a minor planet orbiting the Sun. It is located in the Main Belt. In light of the practice of the discover ca. 1904 to name his asteroids after female characters in opera, it is likely that Ortrud is named after a character in Richard Wagner's opera Lohengrin.
