Seán Dunne (18 December 1918 – 25 June 1969) was a trade union leader and Irish Labour Party politician.
As a Republican, he was interned in the Curragh and Arbour Hill Prison for the first two years of the Second World War, rejoining the WUI on his release.
[3] Dunne first stood for election to Dáil Éireann in the Dublin County constituency at the by-election held on 29 October 1947, as a Labour Party candidate, following the death of Fianna Fáil TD Patrick Fogarty.
He finished last of the four candidates; the seat was won by Seán MacBride, leader of the new Clann na Poblachta party, who would become Minister for External Affairs in 1948.
[3] Dunne died aged 50 on 25 June 1969, only seven days after being returned at the 1969 general election for the Dublin South-West constituency, before he could sign the roll in the 19th Dáil.
