Alfredo Rodrigo Duarte ComIH, better known as Alfredo Marceneiro, was a Portuguese fado singer. His stage name is derived from his original profession as a woodworker. Marceneiro is considered a standard against whom generations of fado singers are still measured today.
On 10 June 1984 he was awarded posthumously Commander of the Order of Infante D. Henrique by the President of the Portuguese Republic, Ramalho Eanes.
