William Pulteney, 1st Earl of Bath, English politician, Secretary at War (died 1764)

William Pulteney, 1st Earl of Bath, was an English Whig politician and peer who sat in the British House of Commons from 1707 to 1742 when he was raised to the peerage as the Earl of Bath by George II of Great Britain. He is sometimes represented as having served as First Lord of the Treasury and Prime Minister of Great Britain as part of the short-lived ministry in 1746, although most modern sources do not consider him to have held the office.

The secretary at war was a political position in the English and later British government, with some responsibility over the administration and organization of the Army, but not over military policy. The Secretary at War ran the War Office. After 1794 it was occasionally a Cabinet-level position, although it was considered of subordinate rank to the secretary of state for war. The position was combined with that of secretary of state for war in 1854 and abolished in 1863.
