Johann Carl Gottfried Loewe (; 30 November 1796 – 20 April 1869), usually called Carl Loewe (sometimes seen as Karl Loewe), was a German composer, tenor singer and conductor. In his lifetime, his songs were well enough known for some to call him the "Schubert of North Germany", and Hugo Wolf came to admire his work. He is less known today, but his ballads and songs, which number over 400, are occasionally performed.
