The Dalrymple-Hay Baronetcy, of Park Place in the County of Wigtown, is a title in the Baronetage of Great Britain.
On inheriting his father-in-law's estates in 1794 he assumed by Royal licence the additional surname of Hay.
His grandson, the third Baronet (who succeeded his father), was an Admiral in the Royal Navy and Conservative politician.
James Reginald Maitland Dalrymple-Hay (1858–1924), eldest son of the aforementioned Colonel George James Dalrymple-Hay, second son of the second Baronet, was a Brigadier-General of the Jamaica Forces.
The heir presumptive to the baronetcy is Ronald George Inglis Dalrymple-Hay (born 1933).
