Baron Wharton is a title in the Peerage of England. It was created in 1544 by letters patent for Sir Thomas Wharton, who had previously served as a Member of Parliament for Cumberland. The fifth Baron, also named Thomas, had a long and distinguished political career, serving at various times as Member of Parliament, Lord Lieutenant of Oxford and Buckingham, Lord Lieutenant of Ireland and Lord Privy Seal. He gained several peerage titles, including: Marquess of Catherlough, Marquess of Wharton, Marquess of Malmesbury, Earl of Wharton, Earl of Rathfarnham, Viscount Winchendon and Baron Trim. His son Philip was made Duke of Wharton, but the title was later forfeit when the Duke of Wharton was declared an outlaw, while his titles he inherited from his father became extinct upon his death.

Thereafter, the Barony of Wharton remained dormant, until 1844, when Charles Kemys-Tynte claimed it. The patent creating the peerage, however, was lost, and the House of Lords errorenously ruled that the barony was one created by writ. As a consequence of their resolution, it was determined that at the death of the Duke of Wharton, the barony fell into abeyance between the Duke's sisters Lucy and Jane. It was further determined that, at Lucy's death in 1739, Jane remained the sole heir, and was therefore entitled to the barony. Finally, it was determined that at Jane's death the Barony again fell into abeyance, where it remained in the nineteenth century.

In 1916, the Sovereign terminated the abeyance in favour of one of Charles Kemys_Tynte's descendants, who was also named Charles. At this baron's death, the title was inherited by his daughter Elisabeth, who became the tenth holder of the barony. At her death in 1974, the barony again fell into abeyance. It was once again revived in 1990, when the abeyance was terminated in favour of Myrtle Robertson. At her death, the barony was inherited by her son Myles.
