Sir Edward Knatchbull, 9th Baronet, was a British Tory politician. He held office under Sir Robert Peel as Paymaster of the Forces between 1834 and 1835 and as Paymaster General between 1841 and 1845.

The Paymaster of the Forces was a position in the British government. The office was established in 1661, one year after the Restoration of the Monarchy to Charles II of England, and was responsible for part of the financing of the British Army, in the improved form created by Oliver Cromwell during the Commonwealth. The full title was Paymaster-General of His Majesty's Forces. It was abolished in 1836, near the end of the reign of William IV, and was replaced by the new post of Paymaster General.
