Joaquim Tenreiro (1906–1992) was among the leading furniture designers and visual artists in mid-20th century Brazil. 

In the early 1940s, Tenreiro was among the first designers in the Brazilian furniture industry to adopt a European modernist vernacular. His initial efforts, including the 1942 "Poltrona Leve," met with considerable success, and in 1943 he established his own firm with factories in Rio de Janeiro and São Paulo. One of his main clients was Brazilian architect Oscar Niemeyer, for whose houses a number of pieces were originally commissioned.

Taking advantage of indigenous Brazilian hardwoods and designing with the Brazilian climate in mind by keeping pieces light, and often using wicker or cane, Tenreiro evolved a distinctive style suited to local conditions.
