Paul de Noailles, 6th Duke of Noailles (4 January 1802 – 29 May 1885) was a French nobleman and historian.
He was the grandnephew of the heirless Jean-Paul-François de Noailles, 5th Duke of Noailles, and succeeded him as Duke of Noailles on the latter's death in 1824, although he did not take his seat among the peers of France until his majority in 1827.
With the duc Pasquier and the duc de Broglie, the duc de Noailles formed the "parti des ducs" (dukes' party).
He was elected a member of the American Antiquarian Society in 1856.
