The Suffren class was a late type of 90-gun ships of the line of the French Navy.

The design was created on 30 January 1824 by an appointed Commission comprising Jean-Marguerite Tupinier, Jacques-Noël Sané, Pierre Rolland, Pierre Lair and Jean Delamoriniere. Intended as successors of the 80-gun Bucentaure class, they introduced the innovation of having straight walls, instead of the tumblehome design that had prevailed until then; this tended to heighten the ships' centre of gravity, but provided much more room for equipment in the upper decks. Stability issues were fixed with underwater stabilisers.
