Baron Templemore, of Templemore in the County of Donegal, is a title in the Peerage of the United Kingdom, since 1975 a subsidiary title of the marquessate of Donegall. It was created on 10 September 1831 for Arthur Chichester, Member of Parliament for Milborne Port and County Wexford. He was the son of Lord Spencer Stanley Chichester, third son of Arthur Chichester, 1st Marquess of Donegall (see Marquess of Donegall for earlier history of the Chichester family). Lord Templemore's son, the second Baron, and grandson, the third Baron, both served as Deputy Lieutenants of County Wexford. The latter was succeeded by his eldest son, the fourth Baron. He served as the Government Chief Whip in the House of Lords between 1940 and 1945. He was succeeded by his second but eldest surviving son, the fifth Baron. In 1975 he succeeded his kinsman as seventh Marquess of Donegall. For further history of the titles, see Marquess of Donegall.
Two other members of this branch of the Chichester family may also be mentioned. The Honourable Augustus George Charles Chichester (1822–1896), second son of the first Baron, was a Lieutenant-General in the 77th Foot. The Honourable Sir Gerald Henry Crofton Chichester (1886–1939), second son of the third Baron, was private secretary to Queen Mary between 1935 and 1939.
"Templemore" refers to a civil parish now located in the city of Derry, County Londonderry, Northern Ireland (in contrast to the territorial designation of the barony). Hence, the title does not refer to the more well-known Templemore, County Tipperary.
