There have been two baronetcies created for persons with the surname Mildmay, one in the Baronetage of England and one in the Baronetage of Great Britain. Both are extinct. The Mildmay Baronetcy, of Moulsham in the County of Essex, was created in the Baronetage of England on 29 June 1611 for Thomas Mildmay, previously Member of Parliament for Maldon. He was the grandson of Sir Thomas Mildmay, Auditor of the Court of Augmentation, elder brother of Sir Walter Mildmay. The title became extinct on his death in 1626. Mildmay's brother Henry Mildmay claimed the barony of FitzWalter. In 1667 Henry's grandson Benjamin Mildmay was confirmed in the title.
