William Francis Hare, 5th Earl of Listowel, GCMG, PC (28 September 1906 – 12 March 1997), styled Viscount Ennismore between 1924 and 1931, was an Anglo-Irish peer and Labour politician.

He entered the House of Lords on the death of his father in November 1931, by right of the United Kingdom peerage of Baron Hare, and made his maiden speech in March of the following year.

[citation needed] When Labour came to power in 1945 under Clement Attlee, Listowel was appointed Postmaster General, a post he held until April 1947, and was briefly Minister of Information between February and March 1946, when the office was abolished.

He continued to serve under Attlee as Minister of State for Colonial Affairs from 1948 to 1950 and as Joint Parliamentary Secretary to the Ministry of Agriculture and Fisheries from 1950 to 1951.
