Millalelmo or Millarelmo (died 1570) was a Mapuche military leader in the second great Mapuche rebellion that began in 1561 during the Arauco War. Probably the toqui of the Arauco region, he commanded the Mapuche army of that area at the siege of Arauco from May 20 to June 30, 1562. He is said to have died in 1570 and ordered his body to be burned, so that he might rise up into the clouds and keep up the war against the dead Spaniards whom he expected to find there.
