Agnes "Nan" Paterson Hardie (5 October 1885 – 27 June 1947) was a Scottish labour movement activist.

She accompanied her father on many speaking trips, including one to Nova Scotia in 1912, until 1915 when he became ill; Nan and her mother looked after him until he died, later in the year.

In 1935, she succeeded her husband as provost, and the two together waged a long campaign for slum clearance and their replacement with council housing.

[2] Hardie took a particular interest in children's activities, founding a park and lido in the town, and also promoted cycling.

Instead, the council persuaded her to take a leave of absence, but the process of caring for him damaged her own health, and she died in June 1947.
