Elizabeth "Beth" Santos Leal de Carvalho (May 5, 1946 – April 30, 2019) was a Brazilian samba singer, guitarist, cavaquinist and composer.

She started playing the guitar as a teenager, and got involved with the emerging Bossa Nova movement, winning a nationwide song contest on TV at the age of 19.

Following a 1967 album, "Muito Na Onda," with the project 'Conjunto 3D,' Carvalho did her first solo record, 1968's "Andança", and carried the song of the same name to victory in a larger festival, which brought her to prominence.

Carvalho is a very important artist in the history of samba, as she celebrated and brought the spotlight to the work of legendary composers such as Cartola, Nelson Cavaquinho & Guilherme de Brito when they weren't receiving the attention they deserved.

With a career that spanned 40 years, she was a historical figure in Brazilian culture, and recognized as the female sambista with the most substantial opus in Brazil, without diminishing other stars as Clara Nunes and Daniela Mercury.
