Maria Lucília Estanco Louro (1922–2018) was a Portuguese pacifist and opponent of the authoritarian Estado Novo regime, who became known as a teacher and political activist.

Her thesis, entitled "Paul Gauguin seen in the light of Characterology - Life and Work", sparked controversy as she was the first in the Faculty to write about Art, then considered then a poor relative of History.

[1][2][3] Between 1940 and 1944 Louro was a member of the board of the Associação Feminina Portuguesa para la Paz (Portuguese women's peace association - AFPP) and its Secretary for three of those years.

With Cândida Ventura, a colleague from the Faculty of Arts of Lisbon, she collaborated in the mobilization of artists, writers, actors and poets to contribute to the work of the AFPP.

On her 90th birthday, Louro was honoured by Portugal's Não Apaguem a Memória movement (Don't erase the memory - NAM), which works to ensure that the events of the struggle against the Estado Novo are remembered.
