The Keeper of the Privy Purse and Treasurer to the King/Queen (or Financial Secretary to the King/Queen) is responsible for the financial management of the Royal Household of the Sovereign of the United Kingdom.

In India, a privy purse was a payment made to the ruling families of erstwhile princely states as part of their agreements to first integrate with India in 1947 after the independence of India, and later to merge their states in 1949, thereby ending their ruling rights.
