Pierre Garnier, comte de Laboissière (11 March 1755 – 14 April 1809) was a French army general who commanded an infantry division during the War of the Second Coalition. After enrolling in a military academy in 1769, he joined a dragoon regiment in 1772 as a sous lieutenant. In 1779 he was promoted to captain. In late 1792 during the War of the First Coalition he was given command of a cavalry regiment with the grade of colonel. While serving in the "Army of the Rhine" he was captured by the Prussians. After a prisoner exchange he was promoted to "général de brigade" in October 1793. Laboissière was promoted to "général de division" in February 1799. He fought at Stockach and led a division at Novi. In the summer and fall of 1799 he fought in several actions near Genoa. Later he commanded troops in Switzerland. Napoleon appointed him to the Sénat conservateur in 1802, awarded him the Commander's Cross of the Légion d'Honneur in 1804 and made him a "comte de l'empire" in 1808. He died in Paris in April 1809. His surname is one of the names inscribed under the Arc de Triomphe, on Column 15.
