Ynys Môn (Anglesey) is a constituency of the National Assembly for Wales. It elects one Assembly Member by the first past the post method of election. Also, however, it is one of nine constituencies in the North Wales electoral region, which elects four additional members, in addition to nine constituency members, to produce a degree of proportional representation for the region as a whole.

It has been represented since 1999 by Ieuan Wyn Jones, the former leader of Plaid Cymru. Jones resigned from the Assembly on 20 June 2013, leaving the seat vacant and triggering a by-election in the constituency which was held on 1 August 2013. Plaid Cymru's candidate Rhun ap Iorwerth comfortably held the seat for the party with a majority of over 9000 votes.
