3rd Battalion, 5th Marines (3/5) is an infantry battalion in the United States Marine Corps. The battalion, nicknamed "Darkhorse", is based at Marine Corps Base Camp Pendleton, California and consists of approximately 1,000 Marines and sailors. They fall under the command of the 5th Marine Regiment and the 1st Marine Division.

3rd Battalion, 5th Marines, along with the 5th Marine Regiment, was first organized on June 8, 1917, as the United States prepared for World War I. The battalion was composed of four companies: the 16th, 20th, 45th and 47th. Six days later, manned by Spanish–American War and Boxer Rebellion veterans along with a large number of raw recruits, they set sail for France. They participated in campaigns and battles such as Bois de Belleau, Vierzy, Château-Thierry, Pont-a-Mousson, Limey Sector, Fleury, Meuse-Argonne, Blanc Mont, St Michiel, Leffincourt and Soissons. The French Government recognized the young battalion by presenting it the Croix de guerre along with the Fourragère and changing the name of a French landmark, Belleau Wood, to "Bois de la Brigade de Marine" or "Wood of the Marine Brigade".
