There have been three baronetcies created for members of the Glyn family, two in the Baronetage of Great Britain and one in the Baronetage of the United Kingdom.

The Glyn Baronetcy, of Ewell in the County of Surrey, was created in the Baronetage of Great Britain on 29 September 1759 for Richard Glyn. He was a banker and also represented the City of London and Coventry in Parliament. In 1942 the title was inherited by Sir Richard Fitzgerald Glyn, 4th Baronet, of Gaunt's House (see below), who became the eighth Baronet of Ewell as well. The ninth baronet was a Conservative politician.

The Glyn Baronetcy, of Gaunt's House in the County of Dorset, was created in the Baronetage of Great Britain on 22 November 1800 for Richard Carr Glyn. He was the fourth son of the first baronet of the 1759 creation. Carr-Glyn was also a banker and sat as a member of parliament for St Ives. In 1798 he served, like his father before him, as Lord Mayor of London. The fourth baronet of this creation succeeded to the Glyn Baronetcy of Ewell in 1942. The titles have remained united ever since. Another member of the Glyn family was George Glyn, 1st Baron Wolverton. He was the fourth son of the first baronet of the 1800 creation.

The Glyn Baronetcy, of Farnborough Downs in the County of Berkshire, was created in the Baronetage of the United Kingdom on 21 January 1934 for Ralph Glyn (a great-grandson of the first Carr-Glyn baronet), who was also later created Baron Glyn.
