Meinhard III (born 1344; died January 13, 1363 in Meran, Tyrol), was the son of Countess Margarete Maultasch of Tyrol and the last member of the Meinhardiner line. After the death of his father Louis of Bavaria in 1361, he ascended to rule, in which he was strongly influenced by his Wittelsbach relatives. His early death induced her mother to give Tyrol to Duke Rudolf IV of Austria.
