Ruy de Moura Belo (27 February 1933, in São João da Ribeira – 8 August 1978 in Queluz) was a Portuguese poet and essayist.
Belo earned a doctorate in the same subject soon afterward, with a thesis entitled Ficção Literária e Censura Eclesiástica, regarding German literary fiction and religious censorship.
During his stay in Rome, Ruy Belo was also a member of the Catholic organization Opus Dei.
In 1961, Ruy Belo quit Opus Dei, and published his first poetry book, Aquele Grande Rio Eufrates.
In June 2003, a statue of Ruy Belo was erected in the Parque dos Poetas in Oeiras.
