Daniel Judson Callaghan (26 July 1890 – 13 November 1942) was an admiral in the United States Navy during World War II.

Born in San Francisco, Calif., 26 July 1890, Callaghan graduated from the United States Naval Academy in 1911. His prewar service included command of Truxtun (DD-14), staff duty afloat and ashore, and duty as Naval aide to the President . He commanded San Francisco (CA-38) from May 1941 to May 1942, then served as chief of staff to Commander, South Pacific area and South Pacific Force.

Rear Admiral Callaghan was killed in action in the bitter Naval Battle of Guadalcanal 13 November 1942 while commanding forces that helped turn back a far stronger Japanese fleet. He was posthumously awarded the Congressional Medal of Honor for extraordinary heroism during the action in which he gave his life.

Two ships have been named USS Callaghan for him.
