Camp Lemonnier is a United States Naval Expeditionary Base, situated next to Djibouti–Ambouli International Airport in Djibouti City, and home to the Combined Joint Task Force – Horn of Africa (CJTF-HOA) of the U.S. Africa Command (USAFRICOM). It is the only permanent U.S. military base in Africa. The camp is operated by U.S. Navy Region Europe, Africa, Southwest Asia; CJTF-HOA is the most notable tenant command located at the facility as of 2008.
Camp Lemonnier was originally established as garrison for the French Foreign Legion. The base was leased by Djibouti to the United States in 2002, along with the right to use the neighboring airport and port facilities. The base supports Operation Enduring Freedom – Horn of Africa (OEF-HOA) and is the centerpiece of a network of around six U.S. drone and surveillance bases stretching across the continent. The latter air bases are smaller and operate from remote hangars situated within local military bases or civilian airports. Due to its strategic location, Camp Lemonnier also serves as a hub for aerial operations in the Persian Gulf region.

Djibouti is strategically located by the Bab-el-Mandeb Strait, which separates the Gulf of Aden from the Red Sea and controls the approaches to the Suez Canal. As a result, the country hosts many other foreign military bases, including a Chinese naval base, a French airbase, an Italian Support Base and a Japanese base. Unlike French troops, who are allowed to enter Djibouti city and interact with the locals, US troops may only leave Camp Lemonnier by special permission, and most of Djibouti City is off limits.

History
Camp Lemonnier is located in the town of Ambouli on the southern side of the Djibouti–Ambouli International Airport, between the runway overflow areas and a French military munitions storage facility. After use by the French Foreign Legion, the facility was operated by the Djibouti Armed Forces.

Lemonnier originally belonged to the French military, and was named after General Émile-René Lemonnier. Commander of the 3rd Brigade of the Tonkin Division, led with fierce energy the resistance to the Japanese coup d'état in French Indochina. In 2009, after years of misspelling, the U.S. Navy officially changed the camp's name to properly reflect the spelling of General Lemonnier's name.
Following the September 11, 2001 attacks, the U.S. decided to increase counter-terrorism efforts. At first, this was limited to focused attacks, but in 2002 the U.S. government realized that to reduce extremism would require long term engagement with the local governments and populations. As a result, it established the Combined Joint Task Force-Horn of Africa to conduct stability operations in the area. In November 2002, the CJTF-HOA staff, a Marine-based organization, arrived off the coast of Djibouti aboard , a naval command ship. Djiboutian workers were instrumental in preparing the newly renovated camp for movement of the CJTF headquarters ashore. More than 1,200 local and third-country national construction and support personnel currently work at the camp. KBR administers the contract for facilities and support operations for the camp.
