Menteith was a character in William Shakespeare's play Macbeth.
He was part of the army which Malcolm and Macduff amassed in order to remove Macbeth from the Scottish throne. Appearing in Act V Scene IV, at its beginning he answered Siward's question as to what wood was before their troops by replying with Great Birnam Wood. Menteith and the other soldiers used branches and leaves from the forest as camouflage so that their approach would not be suspected. Their forces were ultimately victorious with Macbeth "fight[ing] and los[ing]" due to not realising his men were outnumbered until it was too late, unpreparedness which was caused by his misinterpretations of the Weird Sisters' prophecies in Act IV.
