Vice Admiral Carl Harald Åkermark (12 September 1873 – 1 November 1963) was a senior Swedish Navy officer.

He served on numerous vessels, including the gunboats Skuld and Skäggald and the coastal defense ship HSwMS Drottning Victoria.

He subsequently headed the Royal Swedish Naval Materiel Administration and achieved the rank of vice admiral in 1934 before retiring in 1938.

During World War II, Åkermark returned as Commanding Admiral of the West Coast Naval District (1939–1942).

His contributions to naval strategy and education, including involvement in various expert investigations, left a lasting legacy in Swedish maritime defence.

In addition, his grandfather Theodor Wilhelm Tranchell, founder of Lindholmen's workshop, shipowner and longtime chairman of the Seamen's Association in Gothenburg, was anxious to familiarize his grandchildren with the sea.

This was, well due to his young age, not expected either, and it was decided that he would go to the preparatory naval school for another year and live with senior lecturer Huldt.

Åkermark served as a teacher at the Royal Swedish Naval Staff College between 1914 and 1919, during which time he was promoted to lieutenant commander in 1916.

He was promoted to captain in 1923 and then served as head of the Military Office of the Minister for Naval Affairs (Sjöförsvarets kommandoexpedition) from 1923 to 1927.

He was promoted to vice admiral in 1934 and retired in 1938, afterwich he served as chairman of the Maritime Safety Inquiry (Sjöfartsskyddsutredningen) in 1939.

During World War II, Åkermark was called up and served as Commanding Admiral of the West Coast Naval District from 1939 to 1942.

Behind his reserved and even withdrawn, almost shy exterior hid a will of steel, which, if necessary, could radiate an authority and power that did not require any external manifestations to assert itself.
