Francisco María de Paula Téllez-Girón y Benavides (11 March 1678 in Madrid – 3 April 1716 in Paris), 6th Duke of Osuna, 6th Marquess of Peñafiel, 10th Count of Ureña, was a Spanish noble, diplomat and a Grandee of Spain.
He inherited the titles of Chief Notary of the Kingdom of Castile (Notario mayor del reino) and Chief Waiter of the King (Camarero mayor del Rey) upon the death of his father in 1694.
On 12 December 1700, he welcomed and made the corresponding obeisances to the new sovereign Philip V of Spain at the Spanish-French border and accompanied the new King on his travel to Madrid.
At the end of 1711, the King elected him Ambassadeur extraordinaire and first Plenipotentiary for the Congress of Utrecht.
The Duke would now be assigned as Ambassador to the Court of Paris, but he died there on 13 April 1716, at just 38 years of age.
