Mair Eluned Morgan, Baroness Morgan of Ely, PC (born 16 February 1967) is a Welsh politician who has served as First Minister of Wales and Leader of Welsh Labour since 2024. Morgan is the first woman and the first member of the House of Lords to serve as First Minister. Before becoming First Minister, she served as Cabinet Secretary for Health and Social Care from 2021 to 2024.

Morgan has been a member of the House of Lords since 2011, a member of the Senedd (MS) since 2016 and was a member of the European Parliament (MEP) from 1994 to 2009. She is currently on leave of absence from the House of Lords.

A Welsh speaker, Morgan served as Minister for the Welsh Language from 2017 to 2021 as well as Minister for Mental Health and Wellbeing from 2020 to 2021.

As leader of Welsh Labour and First Minister, Morgan has revived Welsh Labour's clear red water strategy used by some of her predecessors, shifting Welsh Labour back to the political left and distancing it from the centrist UK Labour leadership of Keir Starmer, criticising some of the policies implemented by Starmer's government.

Morgan was born and brought up in Ely, Cardiff, the daughter of Bob Morgan and Elaine Morgan. She was educated at Ysgol Gyfun Gymraeg Glantaf, as well as, through a scholarship, the independent United World College of the Atlantic, and later gained a degree in European Studies from the University of Hull.

Morgan is married to Rhys Jenkins, who is a GP and also a non-stipendiary priest. Morgan's family hails from St David's in Pembrokeshire.

In March 2022, Morgan was banned from driving for six months following repeated speeding fines. The offence which took her over the 12-point limit was on a 30mph road in Wrexham.

She has been described as a "committed Christian".
