Mayo West was a parliamentary constituency represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas from 1969 to 1997. The constituency was served by 3 deputies (Teachtaí Dála, commonly known as TDs). The method of election was proportional representation by means of the single transferable vote (PR-STV).
The constituency was created under the terms of the Electoral (Amendment) Act 1969, taking in parts of the former Mayo North and Mayo South constituencies, and included Ballinrobe, Belmullet, Castlebar and Westport.[1] With effect from the 1997 general election it was combined with Mayo East to form a new five-seat Mayo constituency.
Following the resignation of Fianna Fáil TD Pádraig Flynn on his appointment as EU Commissioner, a by-election was held on 9 June 1994. The seat was won by the Fine Gael candidate Michael Ring.
Following the death of Fine Gael TD Henry Kenny, a by-election was held on 12 November 1975. The seat was won by the Fine Gael candidate Enda Kenny, son of the deceased TD.
