Denis John Gorey (25 May 1874 – 20 February 1940) was an Irish politician who served for nearly twenty years as Teachta Dála (TD), first as leader of the Farmers' Party, then for Cumann na nGaedheal, and finally for Fine Gael. Gorey was first elected to the 3rd Dáil at the 1922 general election for the Carlow–Kilkenny constituency, taking his seat as leader of the Farmers' Party, which won seven seats. After his death on 20 February 1940 at the age of 65, no by-election was held for his seat, which remained vacant until the 1943 general election.
