Joyce or Joyce Moreno (born January 31, 1948 in Rio de Janeiro, Brazil) is a singer, composer, instrumentalist and arranger. Her trademark was, since the beginning of her career, the feminine language in the first person, in which she was a pioneer: she was the first female Brazilian composer to express herself this way in the history of MPB, paving the way for countless other female composers who would follow.

Joyce has in her baggage an extensive discography and about 400 recordings of her songs by some of the biggest names in Brazilian popular music, such as Gal Costa, Maria Bethânia, Elis Regina, Milton Nascimento, Ney Matogrosso, Edu Lobo, Emílio Santiago, Boca Livre, Mônica Salmaso, Leny Andrade, Nana Caymmi, Zizi Possi, Elizeth Cardoso, Simone and many others. Internationally, she has been recorded by big names like Annie Lennox, Wallace Roney, Omara Portuondo, Black Eyed Peas, David Sanchez, Jon Lucien, Claus Ogerman, Gerry Mulligan, Till Brönner, Flora Purim and others. Her compositions have been used in soundtracks for films (such as Robert Altman's "The Player" and "Legally Blonde"), animations (she participated in the soundtrack of the Japanese anime "Wolf's Rain" in partnership with Japanese composer Yoko Kanno), TV shows and theater performances.

She received 4 Latin Grammy nominations and has so far 34 individual CDs and 2 DVDs, besides compilations and participations. Currently, her work also follows an international path, with world tours every year and recordings of new albums in different countries, without ever losing her Brazilian-feminine identity. She performs annually on the Blue Note circuit in Japan, and in jazz festivals and tours in Europe, the United States, and Canada.
