António Jacinto do Amaral Martins (28 September 1924 – 23 June 1991) was an Angolan poet and politician. He was also known by his pseudonym Orlando Tavora.
Jacinto was born in Luanda, Angola, to parents of Portuguese descent. He was raised and studied in the interior of Angola in the remote town of Golungo Alto in Cuanza Norte Province. After having obtained his license in Luanda, he started working as a civil servant. He stood out as a protesting poet, and as a result of his political militancy, was first arrested in 1959. Jacinto was ultimately sent to the Tarrafal concentration camp in Cape Verde from 1961 to 1972. His first book of poems was published in 1961, the same year of his arrest and imprisonment. His imprisonment received international attention, and he was transferred in 1972 to Lisbon where, on parole, he worked as an accountant.
Jacinto escaped in 1973 to join the Popular Movement for the Liberation of Angola (MPLA). As soon as independence was declared in 1975 he served in the cabinet of Agostinho Neto (1922 - 1979), first as Minister of Education and Culture, and as secretary of the National Cultural Council in 1977. He withdrew from politics in 1990 due to advanced age.
Jacinto died in Lisbon, Portugal, in 1991.
