The Tollemache baronetcy, or Talmash, of Helmingham in the County of Suffolk, was created in the Baronetage of England on 22 May 1611 for Lionel Tollemache, High Sheriff of Suffolk in 1609 and 1617.

The 2nd Baronet represented Orford in the House of Commons, from 1621 to 1624, and from 1628 to the personal rule of Charles I. The 3rd Baronet married Elizabeth Murray, 2nd Countess of Dysart, and their son Lionel succeeded to both the baronetcy and earldom.

The baronetcy remained united to the earldom until the death of the 7th Baronet, a younger son of the 4th Baronet, in 1821. The baronetcy then became extinct. As of the earldom of Dysart is extant.
