Admiral Sir (Arthur) Francis Turner KCB DSC (23 June 1912 – 26 October 1991) was a British naval officer.

From 1954 Turner served in the Engineer in Chief's department at Bath, laying the foundation for the Navy's planned maintenance organisation.

In 1970, Turner made naval history by becoming the first officer of a non-executive branch to reach the rank of full Admiral.

He was one of the Navy's first specialists in naval aeronautical engineering and pioneered the introduction of planned maintenance to improve the reliability of the fleet's machinery.

The family settled at Effingham, Surrey where Lady Turner lived in retirement until her death on 30 November 2011, aged 79.
