Admiral Sir Michael Culme-Seymour, 3rd Baronet, GCB, GCVO (13 March 1836 – 11 October 1920) was a senior Royal Navy officer.

[3] He entered the Navy in 1850,[4] and in 1856 served as mate in HMS Calcutta, flagship of the East Indies squadron, which was involved in the Second Opium War.

[4] In July 1877 he transferred to HMS Temeraire and took part in the 1878 passage of the Dardanelles commanded by Vice-Admiral Sir Geoffrey Phipps Hornby.

[4] From 29 July 1879 to 9 May 1882 he was captain of HMS Duke of Wellington,[4] which was the flagship of the officer commanding Portsmouth harbour, Admiral Alfred Phillips Ryder,[4] at the end of which appointment he was promoted to rear-admiral.

[4] From 3 May 1893 to 10 November 1896 he was Commander in Chief, Mediterranean Fleet,[4] replacing George Tryon after the accidental sinking of HMS Victoria in a collision.

[3] His eldest son, Sir Michael Culme-Seymour (1867–1925) succeeded him in the baronetcy, and was himself a senior naval officer.

He was killed during the Second Battle of Ypres on 7 May 1915 leading a company from the QVRs over a trench barricade in an attempt to recapture Hill 60.

However, an 1891 newspaper report later came to light, saying that Mary, who had claimed not to have met George V between 1879 and 1898, had in fact opened a ball at Portsmouth Town Hall on 21 August 1891 by dancing with him.
