Baron Pierre-Jacques-Nicolas Rolland (17 June 1769 – 9 December 1837) was a French naval architect and engineer.
In 1795 he fought the British fleet at the naval battle of Genoa on board the French ship Sans Culotte.
In 1802 the launching (under his direction) of two major ships, the République-Française and the Magnanime, drew the attention of Denis Decrès, Minister of the Navy, and of Napoléon Bonaparte himself to the young engineer.
He therefore ordered him to relocate his office to Paris as shipwright advisor and awarded him the title of "lieutenant-general-inspector of Naval Engineers".
Rolland rose to general inspector of naval constructions ("inspecteur général du génie maritime") during the Bourbon Restoration, and took part in the Commission de Paris.
