Cavan was a parliamentary constituency represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas from 1921 to 1977. The method of election was the single transferable vote form of proportional representation (PR-STV).

From 1921 to 1923, Cavan elected 3 deputies (Teachtaí Dála, commonly known as TDs). This was increased to 4 with effect from the 1923 general election, and reduced to 3 with effect from the 1961 general election to 1977.

At the 1977 general election, the Cavan constituency was combined with Monaghan to form the new 5 seat Cavan–Monaghan constituency.

The constituency consisted of the entire administrative county of Cavan.
