Anne Grenville, Baroness Grenville (née Pitt, September 1772 – June 1864) was an English noblewoman and author, and a member of the Pitt family, which at the time dominated British politics.

The union was supported by her father, Baron Camelford and Grenville's uncle, The Marquess of Buckingham, a dominant figure in the Grenville family who provided a £20,000 dowery.
