Junior commissioned officer (JCO) is a term describing a group of military ranks found in the Indian Army, Pakistan Army, Bangladesh Army and Nepal Army. Those soldiers holding JCO rank receive a commission from the President with commanding power.

During British rule, these officers were known as viceroy's commissioned officers (VCOs) except in Nepal, which was never a British colony. Under the British, there was a clear colonial context, until 1866 VCOs being the highest ranks that most Indians could achieve while most commissioned officers were British.

Psychological terrorism can ruin the soldier's morale and ability to perform on the battlefield and thus psychological counselors for the troops form the ranks of JCOs, who are appointed as Pandits/Maulvis/Priest, others, to care for the religious sites of the Indian Army, provide succor in times of distress, as well as carryout the religious ceremonies in the religious places, as each unit has its own Temple/Mosque/Church.

Senior non-commissioned officers are promoted to JCO rank on the basis of merit and seniority, restricted by the number of vacancies. Junior commissioned officers are treated as a separate class, and hold many additional privileges. In the army, they have a separate mess (the JCOs' mess, the CPOs' mess or the WOs' mess), get well furnished family quarters, and are authorized to travel in AC II tier on the railways.

Due to their long years of service and experience, officers accord JCOs great respect and influence, especially in cases involving the enlisted ranks, their welfare and morale.

The JCO ranks in the Indian Army and Pakistan Army (from highest to lowest) are:

The JCO equivalent (or chief petty officer) ranks in the Indian Navy and Pakistan Navy are:
