William Francis Moran (born 1958)[2] is a United States Navy admiral who served as the 39th Vice Chief of Naval Operations from May 31, 2016, to June 10, 2019.

However, in early July 2019—before he could assume the position on August 1, 2019—he declined the CNO post and retired from the Navy, citing an inspector general investigation into the use of his personal email account for Navy business and "or continuing to maintain a professional relationship with a former staff officer, now retired, who had while in uniform been investigated and held accountable over allegations of inappropriate behavior."

[4] As a flag officer, he served as commander, Patrol and Reconnaissance Group and director, Air Warfare (N98) on the staff of the chief of naval operations.

Serving concurrently as the Deputy Chief of Naval Operations, he was responsible for the planning and programming of all manpower, personnel, training and education resources for the United States Navy.

The OIG determined that Moran's use of a personal email account to send official military communications violated Department of Defense policies.
