On 10 February 2018, McDonald succeeded longtime party leader Gerry Adams as President of Sinn Féin, following a special ardfheis (party conference) in Dublin.[2]

In the 2020 general election, Sinn Féin's performance improved significantly and it was the first time in almost a century that neither Fianna Fáil nor Fine Gael won the most votes. Sinn Féin achieved 37 seats, one behind Fianna Fáil with 38 seats.[3] Following Micheál Martin's appointment as Taoiseach in June 2020, following the formation of a Fianna Fáil, Green Party and Fine Gael coalition, McDonald became Leader of the Opposition. She is the first female to occupy that position and the first to come from a party other than Fianna Fáil or Fine Gael since the Labour Party’s Thomas Johnson in 1927.
