Eleanor Concepcion "Connie" Mariano (born 1955), is a Filipino American physician and retired flag officer in the United States Navy.

She is the first Filipino American and graduate of the Uniformed Services University of Medicine to reach the rank of Rear Admiral in the U.S. Navy as well as the second woman to become Physician to the President, a position that placed her as director of the White House Medical Unit.

Mariano joined the U.S. Navy in 1977, and received a medical degree from the Uniformed Services University of Medicine in 1981, graduating as a lieutenant.

Only a year away from being eligible for release from active duty, she was nominated by her commanding officer to serve as Navy physician to the White House Medical Unit.

She joined the unit in June 1992, serving as a physician to President George H. W. Bush, and was about to be issued new orders to be director of the clinic at the Marine Corps Recruit Depot in San Diego when she was personally selected by the incoming President, Bill Clinton, to be White House Physician and director of the White House Medical Unit.
