The Colombian Navy, officially the Colombian National Navy, also known as the "Armada Nacional" or just the "Armada" in Spanish, is the naval branch of the military forces of Colombia. The Navy is responsible for security and defence in the Colombian zones of both the Atlantic (Caribbean) and Pacific oceans, the extensive network of rivers inside the country, and a few small land areas under its direct jurisdiction.

The Military Forces of Colombia are the unified armed forces of the Republic of Colombia. They consist of the Colombian Army, the Colombian Navy and the Colombian Aerospace Force. The National Police of Colombia, although technically not part of the military, is controlled and administered by the Ministry of National Defence, and national conscription also includes service in the National Police, thus making it a de facto gendarmerie and a branch of the military. The President of Colombia is the military's commander in chief, and helps formulate defense policy through the Ministry of National Defence, which is in charge of day-to-day operations.
