The 1st Marine Infantry Regiment (fr|1<sup>er</sup> régiment d'infanterie de marine, 1<sup>er</sup> RIMa) is a French regiment heir of the colonial infantry. The regiment is one of the French: quatre vieux regiments of the Troupes de Marine, with the 2nd Marine Infantry Regiment 2e RIMa, the 3rd Marine Infantry Regiment 3e RIMa, as well the 4th Marine Infantry Regiment 4e RIMa (dissolved in 1998).

Designated as the 1st Colonial Infantry Regiment (1er RIC) in 1900 whe the colonial infantry was created as part of the Ministry of War (fr|Ministère de la guerre), the regiment was redesignated as a régiment d'infanterie de marine in 1958, when the colonial infantry was redesignated as marine infantry.
The evolution of the unit's name:
The regiment is heir to the 1st Free French Division and the battalion of the Pacific which combat engaged at Bir Hakeim. The Marine Infantry and Pacific Battalion (fr|bataillon d'infanterie de marine et du Pacifique) was issued from the merger, in July 1942, of the 1st Marine Infantry Battalion (fr|1<sup>er</sup> Bataillon d'Infanterie de Marine) and the Pacific Battalion (fr|Bataillon du Pacifique).
In 1846, elements of the 1er RIMa were at Tahiti. The regiment was present in the battle of Fatahua (inscribed on the regimental colors of the 2e RIMa) of December 17, 1846 (3rd Company, Captain Masset).
During the Paris Commune in 1871, the regiment participated with the Armée Versaillaise.
The 3e DIC: Generals Raffanel, Leblond, Goulet (1914), Gadel (1915), Puypéroux (1916–1918).

On May 10, 1940, the 1st Colonial Infantry Regiment was under the command of colonel Fauchon and part of the 3rd Colonial Infantry Division which reinforced the sector of Montmédy.
The 3rd Colonial Division, général Falvy, consisted of the 1st, 21e, 23e R.I.C and 3e and 203e R.A.C.The 3rd Colonial Division disappeared. The division immediately engaged the theatre, in the sector of Sun-sur-Meuse, Stenay, Martincourt, Aviot, Breux north of Verdun, at the level of cote 304 and Mort Homme, lieu of harsh combats in 1916–1917, where combats concentrated. On June 14, the 1er and 23e RIC were engaged in the ravine which separated cote 304 from Mort Homme. At 0630, the cote was crowned, despite a relentless resistance, the armoured contingents crossed the bridge of Bethoncout in direction of Esnes. The bridge was blown-up in the evening and redressed in the same night. The 1st company of the 1er RIC of captain Bertrand counter-attacked. At 17 hours, attacks were ceased. At 19 hours, the French Marines (fr|Marsouis) gave their part to other engagements.
The regiment was made compagnon de la Libération, June 28, 1945.
The regiment was found in A.F.N from 1952 to 1962. Garrisoned in several places, the regiment was part of the 9th Brigade, then 9e DIMa, then 9e BLBMa.
The regiment was deployed to Lebanon at the corps of the Multinational Force in Lebanon in 1983, then United Nations Interim Force in Lebanon UNIFIL in 1984.
