Helena Cidade Moura (1924 – 2012) was a Portuguese teacher, researcher, activist, politician and poet, who played an important role in the struggle to overcome the Estado Novo dictatorship in Portugal.

She is best remembered for the leading role she played in the literacy campaign carried out in Portugal after the 25 April 1974 Carnation Revolution.

[1] Before the overthrow of the Estado Novo on 25 April 1974, Moura worked with institutions and initiatives of the so-called progressive Catholics.

In the 1965 elections she was a signatory of the "Manifesto of the 101", which cited the social doctrine of the Catholic Church and papal encyclicals, such as Pacem in Terris, issued in 1963, to criticise the regime's policy.

Under the Estado Novo little had been done to overcome Portugal's high rate of illiteracy, and addressing this problem became a priority of the democratic governments that replaced it.
