Ruth Brandt (22 June 1936 – 13 August 1989) was an Irish artist and teacher, who was known for drawing inspiration from nature for her work.

Brandt spent a year in Florence, funded through an Italian government grant, and whilst there met fellow Irish artist Michael Kane.

After this point, Brandt divided her time between teaching at NCAD and summer classes for children with her husband, and freelance lettering and illustration.

Such illustration is her work in Sheelah Kirby's 1962 The Yeats country and John Irvine's 1964 A treasury of Irish saints.

Other McCormick buildings that Brandt worked on include the stained-glass window design for the Oratory of the Resurrection of Our Lord, Artane, Dublin, and a sculpture for the Met Éireann office, Glasnevin.
