'''Sub-lieutenant''' is usually a [[junior officer]] rank, used in armies, navies and air forces.

In most armies, sub-lieutenant is the lowest [[commissioned officer]] rank. However, in Brazil, it is the highest [[non-commissioned officer|non-commissioned rank]], and in Spain, it is the second highest non-commissioned rank.

As a naval rank, a sub-lieutenant ranks below a [[lieutenant]].
