Dame Rosemary Janet Mair Butler DBE (née McGrath; born 21 January 1943) is a British politician who served as Presiding Officer of the National Assembly for Wales (now Llywydd of the Senedd) from 2011 to 2016.

[citation needed] At the first Assembly election in 1999, Butler was selected as Labour candidate for Newport West which she won.

Butler was appointed Dame Commander of the Order of the British Empire (DBE) in the 2014 New Year Honours for political and public services, particularly to women.

During the campaign, Rosemary has hosted many high-profile influential speakers at the Senedd, most notably former Prime Minister of Australia, Julia Gillard to talk about gender equality and encourage women to put themselves forward for public appointments.

In October 2014, Rosemary launched a mentoring and development scheme for women who wanted to gain experience in public life and undergo training to help prepare them for decision making roles over a period of 18 months.
