Heather Maud Humphreys (née Stewart, born 1960) is an Irish former Fine Gael politician who served in various cabinet positions from 2014 to 2025.

[5] She is a Presbyterian; her father was a member of the Orange Order, while her grandfather, Robert James Stewart, signed the Ulster Covenant opposing Home Rule in 1912.

[12] After just a few months in the position she became embroiled in controversy over her appointment of John McNulty to the board of the Irish Museum of Modern Art (IMMA) on 12 September 2014 just before his nomination for a Seanad by-election to the Cultural and Educational Panel.

Fianna Fáil leader Micheál Martin said at the "very basic level, she should say what officials in Fine Gael asked her to appoint Mr McNulty to the board of Imma".

In the preparations of the 2016 Easter Rising centenary celebrations, she said: Given my background as a Protestant and an Ulsterwoman who is a proud Irish republican, I appreciate the need to respect the differing traditions on this island.

[17] Following the formation of a Fine Gael minority government in May 2016, she was appointed to the expanded position of Minister for Arts, Heritage, Regional, Rural and Gaeltacht Affairs.

[21] On 27 April 2021, she was assigned the addition position of Minister for Justice on a temporary basis during the maternity leave of Helen McEntee, serving until 1 November 2021.
