A by-election for the Welsh Assembly constituency of Ynys Môn was held on 1 August 2013,^[1] The by-election was triggered following the resignation on 20 June 2013 of its sitting Assembly Member, Ieuan Wyn Jones.^[2]

The election was the third Assembly by-election to be held since its formation in 1999, and the first for over seven years (the previous contest being at Blaenau Gwent in June 2006).

Prior to the by-election, the governing Labour Party held exactly half the Assembly seats, meaning a gain for that party (who have held the equivalent seat in the House of Commons since 2001) would have given the Welsh government a two-seat majority.

Six candidates were nominated for the election.^[3][4][5]

Plaid Cymru held the seat with a greatly increased majority.
