A Dáil by-election was held in the constituency of Clare in Ireland on Thursday, 14 March 1968, to fill a vacancy in the 18th Dáil. It followed the death of Fine Gael Teachta Dála (TD) William Murphy on 16 November 1967.

The writ of election to fill the vacancy was agreed by the Dáil on 21 February 1968.

The by-election was won by the Fianna Fáil candidate Sylvester Barrett. It was held on the same day as the 1968 Wicklow by-election.

The surplus votes of Barrett were distributed after he was declared elected, because there was a possibility another candidate could have reached the threshold of a third of a quota. This would have meant their election deposit was returned to them.
