Baron Stourton is a title in the Peerage of England, It was created by patent in 1448 for John Stourton. In 1878, the ancient barony of Mowbray was called out of abeyance in favour of the twentieth Baron Stourton. About two weeks later, the barony of Segrave was also called out of abeyance in his favour. Thereafter, the three baronies have remained united. The formal title is Baron Mowbray, Segrave and Stourton. The family seat, until 1717, was Stourhead. The motto of the family is "Loyal je serai durant ma vie" (French: I will be loyal throughout my life).
