Arthur Cayley Davis (14 March 1893 – 10 February 1965) was an admiral of the United States Navy.

He was head of the Plans Division of the Bureau of Aeronautics from 1936 to 1939, then served as the commanding officer of the seaplane tender USS Langley from 1939 to 1940.

Under his command, USS Langley operated in the United States Atlantic Fleet from February to July 1939.

In mid-1940, by-then-Captain Davis became the aviation officer on the staff of the Commander-in-Chief, Pacific Fleet, the position he held when the Japanese attacked Pearl Harbor, Hawaii, on 7 December 1941.

After his promotion to rear admiral, Davis received the Navy Cross for his actions aboard USS Enterprise on 24 August, the citation for the award read, "By his remarkable seamanship, resourcefulness and his outstanding skill in maneuvering his ship, Rear Admiral Davis met the vigorous Japanese dive-bombing attack coolly and courageously, holding the damage by bomb hits to the Enterprise to a minimum and, in turn, inflicting heavy casualties on the attacking enemy planes."

[1] Davis won over Spruance with his competence and congeniality and was described as a "lean, rough, aggressive leader" who "moved decisively and intelligently."

He served as Deputy United States Representative to the Standing Group, North Atlantic Treaty Organization until 16 August 1953.

In addition, USS Enterprise was awarded a Presidential Unit Citation for the period 7 December 1941 to 15 November 1942, which included Davis's time in command.
