A Dáil by-election was held in the constituency of Dublin County South in Ireland on Wednesday, 2 December 1970, to fill a vacancy in the 19th Dáil. It followed the resignation of Fianna Fáil Teachta Dála (TD) Kevin Boland on 4 November 1970.
In May 1970, in the midst of the Arms Crisis, Taoiseach Jack Lynch sacked two cabinet ministers, Charles Haughey and Neil Blaney. Kevin Boland resigned as Minister for Social Welfare. Haughey and Blaney were later charged. On 23 October 1970, after the second of two trials, all defendants were acquitted.
