James Smith-Stanley, Lord Strange (1716–1771) was commonly known by that title, though neither he nor his father had any claim to it. He was the eldest son of Edward Stanley, 11th Earl of Derby, whose predecessor's heirs had used that courtesy title, but the right to two successive baronies Lord Strange had descended to daughters, when the earldom had passed to the heir male.

Baron Strange is a title which has been created four times in the Peerage of England. Two creations, one in 1295 and another in 1326, had only one holder each, upon whose deaths they became extinct. Two of the creations, that of 1299 and that of 1628, are extant. The surname Le Strange was Latinized as Extraneus. The arms of Le Strange of Knockin Castle in Shropshire were: Gules, two lions passant argent.
