Vilém Heš, German Wilhelm (Willy) Hesch, (3 June 1860, in Týnec nad Labem – 4 January 1908, in Vienna) was a Czech operatic bass. He notably enjoyed a close artistic partnership with Gustav Mahler, singing in his opera companies in Hamburg and Vienna. He had a beautiful rich vocal tone, although at times his voice would take on a harsher quality in heavier repertoire.
