The Mostyn baronets are two lines of Welsh baronets holding baronetcies created in 1660 and 1670, both in the Baronetage of England. One creation is extant as of 2008. The two lines are related and both claim descent from Edwin of Tegeingl a 11th century lord of Tegeingl, a territory which approximates modern Flintshire.
