Princess Adélaïde Diane Mancini called (27 December 1742 – 2 May 1808), Mancinette (27 December 1742 – 2 May 1808), was a French court official and member of the House of Mancini.

She is known to have curbed the expenses of the queen's wardrobe during her time in office and created order in the queen's economy, which was however ruined by her successor.
