Donegal is a parliamentary constituency which is represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas, since the 2016 general election. The constituency elects 5 deputies (Teachtaí Dála, commonly known as TDs). The method of election is the single transferable vote form of proportional representation (PR-STV). It covers the current County Donegal with the exception of nine southern electoral divisions which are part of the neighboring Sligo–Leitrim constituency.

The Donegal constituency was created in 1921 under the Government of Ireland Act 1920, for the 1921 election to the House of Commons of Southern Ireland, whose members formed the 2nd Dáil. It elected 6 deputies in 1921, and again at the 1922 general election. It covered the whole territory of County Donegal in north-west Ireland.

Under the Electoral Act 1923, the constituency's boundaries remained unchanged, and were defined simply as "the administrative county of Donegal". However, its representation was increased from 6 to 8 seats.

The Donegal constituency was abolished by the Electoral (Revision of Constituencies) Act 1935, with effect from the 1937 general election. It was replaced by two new constituencies: the 4 seat Donegal East and the 3 seat Donegal West.
