Christian Theodor Weinlig (July 25, 1780 – March 7, 1842) was a German music teacher, composer, and choir conductor in Dresden and Leipzig.
Born in Dresden, Weinlig received his musical training from his uncle Christian Ehregott Weinlig and from Stanislao Mattei in Bologna, where he was a member of the Accademia Filarmonica. From 1814 to 1817 he worked as Cantor of the Kreuzkirche in Dresden. In 1823, he became Cantor of the Thomanerchor in Leipzig, an office he kept until his death.
Among his most well-known pupils were pianist Clara Schumann and composer Richard Wagner; he taught Wagner at Saint Thomas school in Leipzig.
