Lynne Neagle (born 18 January 1968) is a Welsh Labour & Co-operative politician serving as Cabinet Secretary for Education since 2024. Born in Merthyr Tydfil, Glamorgan, Wales, Neagle has been the Member of the Senedd (MS) for the constituency of Torfaen since the Senedd was established in 1999.

Neagle was educated at Cyfarthfa High School, Merthyr Tydfil, and the University of Reading, where she read French and Italian.

She is a former Voluntary Sector Carer and Careers Development Officer. Neagle was also a research assistant to Glenys Kinnock MEP from 1994 to 1997.

Neagle was elected to the Senedd in 1999 as a Labour candidate to represent Torfaen. Neagle was an ally of Alun Michael during his leadership of the Welsh Labour party.

Later in the first term, she was appointed to the role of Chair of the Welsh Labour group in the Senedd. She initially opposed coalition with the Welsh Liberal Democrats, and supported a motion that would have required any coalition from the 2003 Assembly election onward to go to a vote of Welsh Labour members. However, she later said that the "alternative was worse" and supported the formation of a coalition.

She was occasionally critical of policy of the Morgan government, including the party's health policy, around a lack of targets and around funding, and the elimination of school league tables.

She was re-elected in 2003 with a majority of 6,964 votes. She was a member of the Standards committee during the Second Assembly.

Neagle was critical of the creation of a coalition with Plaid Cymru. In emails leaked to the Western Mail at the time, she stated she wanted "no stone left unturned" in terms of avoiding a Labour-Plaid coalition, by re-engaging the Welsh Liberal Democrats in talks. She wrote to criticise the coalition in the Western Mail, saying "The facts as I see them in the One Wales document points to a fundamental and detrimental change in direction for Welsh politics. They are not facts I can ignore."
