There have been two baronetcies created for persons with the surname Warren, one in the Baronetage of Great Britain and one in the Baronetage of Ireland. As of 2008 one creation is extinct while the other is dormant.
The Warren Baronetcy, of Little Marlow in the County of Buckingham, was created in the Baronetage of Great Britain on 1 June 1775 for the naval commander and politician John Borlase Warren. He was a descendant of Anne, daughter of Sir John Borlase, 1st Baronet (see Borlase baronets), hence his middle name. Warren had no surviving male issue and the title became extinct on his death in 1822.
The Warren Baronetcy, of Warren Court's in the County of Cork, was created in the Baronetage of Ireland on 7 July 1784 for Robert Warren, High Sheriff of County Cork in 1752. The fifth Baronet served in the Crimean War and in the Indian Rebellion of 1857 and was High Sheriff of County Cork in 1867. The eighth Baronet was a Colonel in the Royal Army Service Corps and served as Chief Constable of Buckinghamshire in 1928. The title became dormant on the death of the ninth Baronet in 2006.
Five other members of the family may also be mentioned. Thomas Warren, third son of the first Baronet, was a Member of Parliament. His ninth son Brisbane Warren was the father of the Very Reverend Thomas Brisbane Warren, Dean of Cork. Richard Warren, second son of Reverend Robert Warren, eldest son of Reverend Robert Warren, fifth son of the first Baronet, was a major-general in the British Army. Augustus Edmund Warren, second son of Richard Benson Warren, seventh son of the first Baronet, was also a major-general in the British Army. Robert Warren, son of Captain Henry Warren, eighth son of the first Baronet, was a politician and judge.
