Aurélio Buarque de Holanda Ferreira (May 3, 1910 – February 28, 1989) was a Brazilian lexicographer, philologist, translator, and writer, best known for editing the Novo Dicionário da Língua Portuguesa, a major dictionary of the Portuguese language.

In 1923 he moved to the state capital Maceió, where, at only 14 years of age, he gave private lessons of Portuguese language.

In 1942 he published a book of short stories, Dois Mundos ("Two Worlds"), which earned him a prize by the prestigious Brazilian Literary Academy.

Between 1947 and 1960, Aurélio authored various texts for the Conto da Semana ("Weekly Tale") section of the newspaper Diário de Notícias.

He was elected a member of the Brazilian Literary Academy on May 4, 1961, and inaugurated on December 18, 1961, taking over seat number 30, formerly of Antônio Austregésilo.
