Adelina Abranches OSE (15 August 1866 – 21 November 1945) was a Portuguese stage actress born in Lisbon.

A theatrical child prodigy, she first performed at just four years of age in the piece Meninos Grandes ("Big Kids") at the National Theatre D. Maria II in Lisbon.

She then began a brilliant career in Rio de Janeiro, playing, in spite of her small stature, drag roles, soubrettes, and ladies of the night.

In 1930 she played Aunt Aurélia in the Portuguese silent film, Maria do Mar, directed by José Leitão de Barros.

In Portugal she worked under Amélia Rey Colaço alongside actors such as Eunice Muñoz and Estêvão Amarante.
