A warrant officer (WO) is an officer in a military organisation who is designated an officer by a warrant, as distinguished from a commissioned officer who is designated an officer by a commission, and a non-commissioned officer who is designated an officer, often by virtue of seniority.

The rank was first used in the (then) English Royal Navy and is today used in most services in many countries, including the Commonwealth nations and the United States.

Outside the United States, warrant officers are included in the "Other Ranks" (OR) category, equivalent to the US "E" (Enlisted) category and rank between non-commissioned officers and commissioned officers. The warrant officers in Commonwealth navies rank between chief petty officer and sub-lieutenant, in Commonwealth air forces between flight sergeant and pilot officer, and in Commonwealth armies between staff sergeant and second-lieutenant.

Warrant officers in the United States are classified as officers and are in the "W" category (NATO "WO"); they are technical leaders and specialists. Chief warrant officers are commissioned by the President of the United States and take the same oath as regular commissioned officers. They may be technical experts with a long service as enlisted personnel, or direct entrants, notably for U.S. Army helicopter pilots.
