Algernon Maudslay CBE (10 January 1873 – 2 March 1948) was a British yachtsman and an administrator of refugee, Red Cross and relief organisations.

Maudslay represented Great Britain in sailing competitions at the 1900 Summer Olympics in Meulan, France.

He was active in the Anglo-Belgian Union and served in British and international Red Cross and relief organizations during the post-war decades.

The gold medal for first place was awarded to the British boat Scotia, crewed by Maudslay as helmsman, and possibly also Lorne Currie and John Gretton.

[3][9] In 1917 he was appointed a Commander of the Order of the British Empire in recognition of his service in the Belgian War Refugees Committee.

[10][11] Maudslay was the prime mover in the formation of the Anglo-Belgian Union in July 1918 "to maintain and foster the friendly relations between the British and Belgian peoples that had sprung up during the war".

[15] In 1920 Maudslay joined a group called the 'Liberty League', described as an association "to combat the advance of Bolshevism in the United Kingdom and throughout the Empire".

[16][B] Maudslay, representing the Royal Thames Yacht Club, was the honorary secretary of a special committee formed to carry out the arrangements for a challenge received from the Seawanhaka Yacht Club of America, based on Staten Island, to race for the British-American Cup in The Solent, between the Isle of Wight and the mainland, in August 1921.

[22] Algernon Maudslay died on 2 March 1948 at 'The Down House', Itchen Abbas, near Winchester in Hampshire, aged 75.
