Carlow–Kilkenny is a parliamentary constituency represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas.

The constituency elects five deputies (Teachtaí Dála, commonly known as TDs) on the system of proportional representation by means of the single transferable vote (PR-STV).

^ *: Outgoing TD Séamus Pattison was Ceann Comhairle at the dissolution of the 28th Dáil and therefore deemed to be returned automatically.

The poll was postponed due to the death of outgoing Fine Gael TD Eamonn Coogan during the campaign.

A by-election was held on 3 November 1927 and the seat was won by the Cumann na nGaedheal candidate Denis Gorey.
