Sir John de Menteith (c. 1275 – c. 1323) was a Scottish nobleman. He was born to Mary, Countess of Menteith and her husband Walter "Bailloch" Stewart, Earl of Menteith jure uxoris. He and his older brother, Alexander, Earl of Menteith, replaced their paternal Stewart surname in favour of Menteith, which earned him the nickname Fause (False) Menteith. John possessed the land of Ruskie, Stirlingshire, Wyntoun, whose "Metrical Chronicle" was written in 1418, says: "Schyre Jhon of Menteith in tha days Tuk in Glasgow William Walays; And sent hym until Ingland sune, There was he quartayrd and undone."
