Evangelina Sobredo Galanes, known as Cecilia, (October 11, 1948 – August 2, 1976) was a Spanish singer-songwriter. She took her stage name from the song "Cecilia" by Simon and Garfunkel.

The daughter of diplomats, she was born in Madrid, spent her childhood in several countries (Spain, The United Kingdom, The United States, Jordan, Portugal) and was raised by an American nun. She attained a bachelor's degree in law in Spain before deciding to dedicate herself to music and composition. Her ironic and lyrical songs, sung in a tiny voice, contributed to the existentialist and feminist movements of Spanish canción protesta (protest songs) of the 1960s and 1970s.
