Elis Regina Carvalho Costa (Portuguese pronunciation: ; March 17, 1945 – January 19, 1982), popularly known as Elis Regina, was a Brazilian singer of popular and Jazz music.

She became nationally renowned in 1965, after singing "Arrastão" (composed by Edu Lobo and Vinícius de Moraes) in the first edition of TV Excelsior festival song contest, and soon joined O Fino da Bossa, a television program on TV Record. Elis was noted for her vocalization, as well as for her personal interpretation and performances in shows. She recorded several successful compositions, such as "Como nossos pais" (Belchior), "Upa Neguinho" (E. Lobo and Gianfrancesco Guarnieri), "Madalena" (Ivan Lins), "Casa no Campo" (Zé Rodrix and Tavito), "Águas de Março" (Tom Jobim), "Atrás da porta" (Chico Buarque and Francis Hime), "O bêbado e a equilibrista" (Aldir Blanc and João Bosco), "Conversando no bar" (Milton Nascimento), etc.

Her death, at the age of 36, shocked Brazil. She has frequently been regarded as the greatest Brazilian singer of all time by critics, musicians, and commentators.
