Claremorris (/ˌkleɪrˈmɒrɪs/; Irish: Clár Chlainne Mhuiris[3]) is a town in County Mayo in the west of Ireland, at the junction of the N17 and the N60 national routes.

[citation needed] In 1822, a Roman Catholic Chapel was built, which was later demolished to make way for the town hall.

[citation needed] At the 2022 census, Claremorris had a total population of 3,857 people,[5] consisting of 1,821 males and 2,036 females.

Gaelscoil Uileog de Búrca, in nearby Loughanamon, provides primary education through the Irish language.

[citation needed] Local events include Claremorris Open Exhibition (an annual arts exhibition in the town held since 1978),[citation needed] and the Claremorris Drama Festival (an annual drama festival held since 1970).

[citation needed] A rugby club, Claremorris Colts RFC, was established in 2009 and meets at the Mount St Michael Convent Girls School pitch.

[citation needed] A swimming club trains at the Claremorris Leisure Centre, and incorporates water polo.

[citation needed] The Claremorris Leisure Centre opened in 2009 and has a 25-metre, 6 lane, short course competition pool.

The new 16 km road bypassed one of Ireland's most treacherous national routes, as the original 11-kilometre (7 mi) stretch between Claremorris and Knock had a very high accident.

However, as of December 2023, no date for this proposed development had been identified, with the "all-island strategic rail review" recommending that related works by "commenced by 2030".

[21] Claremorris is home to one of Ireland's eight inland weather observing stations, located 2 kilometres from the town centre.

Weather reports from Claremorris and Blacksod Lighthouse (located on the west coast of Mayo) played a significant factor in selecting the date of launch for the D-Day landings in June 1944.

In 1949, it was decided that the Irish Meteorological Service needed observations on an hourly basis from inland stations like Claremorris.

In 1996, staff were relocated to Ireland West Airport and it now operates automatically with data uploaded to Dublin.
