The Pacificateur was a Bucentaure-class 80-gun ship of the line of the French Navy, designed by Sané.

[1] Commissioned in Antwerp in 1814, Pacificateur remained anchored at the entrance of the harbour to protect it until the Bourbon Restoration.

In September 1814, she arrived in Brest, where she stayed until she was condemned, in 1824.

In January 1824, Pacificateur was used as a target ship to test new 22 cm canon-obusiers invented by Henri-Joseph Paixhans.

[2] The wooden sides of Pacificateur sustained devastating damage, starting the decline of wooden warships and rise of the ironclads.
