Daphne Caine will take up the position Minister for Education, Sport and Culture with immediate effect.
It comes as Chief Minister Alf Cannan has announced a strategic mid-term change to the Council of Ministers.
Mrs Caine replaces Julie Edge, who had held the post since the start of the current administration.
The Chief Minister said: ‘I believe it is an appropriate time to make this change and to introduce a fresh perspective to the Council of Ministers. I need to balance the need for continuity with opportunities to allow for fresh thinking as the administration pursues its objectives around the Island Plan and Economic Strategy.’
Garff member Mrs Caine was first elected in 2016 and has served on a range of Tynwald and Council of Ministers committees and as a Member of the Department for Enterprise, and was appointed Chair of the Isle of Man Climate Change Transformation Board in 2021.
