The Diadème was an 86-gun Bucentaure-class 80-gun ship of the line of the French Navy, designed by Sané.

Commissioned in Lorient in January 1812, Diadème was disarmed at the Bourbon Restauration. She had major refits in 1822 and 1833, and was reactivated in 1826 to join the squadron of the Mediterranean.

From 1856, she was used as a barracks hulk.
