Baron Pierre-Jacques-Nicolas Rolland (17 June 1769 – 9 December 1837) was a French naval architect and engineer.
Pierre-Jacques-Nicolas Rolland was born on 17 June 1769 in the harbour town of Brest, into the family of Pierre Nicolas Rolland, engineer-constructor of the Brest Port.
He followed his father's footsteps and in 1785, at the age of 16 entered the service at Rochefort Port.
In 1795 he fought the British fleet at the naval battle of Genoa on board the French ship Sans Culotte.
Ten years later he was already an established engineer and shortly thereafter chief engineer.
In 1808, Bonaparte visited Rochefort's naval dockyard and was highly satisfied with Rolland's work there.
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".
In 1811 he was assigned to go from France to the Kingdom of Holland in order to compare shipbuilding methods between these two countries.
Pierre-Jacques-Nicolas Rolland died in Paris on 9 December 1837.
He was awarded Order of Saint Michael, Order of Saint-Louis in 1817, and Commander Cross of the Legion of Honour in 1831.
