Hugh William Fortescue, 5th Earl Fortescue (14 June 1888 – 14 June 1958), styled Viscount Ebrington from 1905 until 1932, of Castle Hill in the parish of Filleigh, of Weare Giffard Hall, both in Devon and of Ebrington Manor in Gloucestershire, was a British peer, military officer, and Conservative politician.

During the First World War (1914–18) he served in France as a regimental officer for the Scots Greys, followed by the Royal Corps of Signals.

He was admitted to the Privy Council in 1952 and received the very great honour of being appointed a Knight Companion of the Order of the Garter in 1951.

Although the title passed to his brother on his death, the 5th Earl left his principal and grandest seat, Castle Hill, Filleigh in North Devon, to his elder surviving daughter, Lady Margaret Fortescue (1923–2013).

The 5th Earl Fortescue left his secondary Devon seat, Weare Giffard Hall, to his younger daughter Lady Elizabeth Baxendale (born 1926),[12] who sold it in 1960.
