The following is a list of United States Navy oilers (hull designations AO, AOE, AOL, AOR and AOT). It does not include gasoline tankers (AOG) or submarine oilers (AOSS).
Oilers are considered to be auxiliaries by the US Navy, and this article's lists are thus a subset of this type of ship. All other auxiliaries can be found at List of auxiliaries of the United States Navy, including the gasoline tankers. Tankers commissioned into the Navy for bulk storage at mobile bases by Service Squadrons during World War II were not classed as auxiliaries but as unclassified miscellaneous vessels (IX).
