Francis Annesley, 6th Earl of Annesley (25 February 1884 – 6 November 1914), styled Viscount Glerawly between 1884 and 1908, was an Anglo-Irish peer, Royal Navy officer and pioneer aviator who died in a plane crash at sea.

He was born on 25 February 1884 at Castlewellan, Kilmegan, County Down, Ulster, Ireland.

Before obtaining his age of majority he sailed from Liverpool to Vancouver, around Cape Horn, serving as a sailor before the mast.

Lord Annesley was last seen alive on 6 November 1914 leaving Eastchurch, England, in a Bristol T.B.8 biplane, serial 1220, flown by Flight Lieutenant C.F.

Two German prisoners had been interrogated and it was established that the two aviators had been shot down when a German shell had hit the petrol tank of their aircraft and it had fallen in flames near Diksmuide.
