Mariana Duarte Santos (b. 1995) is a visual artist from Lisbon. She attended Ar.Co (Center for Art and Visual Communication, Lisbon) and develops work of a figurative nature, mainly centered on painting and engraving, heavily influenced by other artistic areas such as cinema and literature.

Her pieces reflect the way she observes and perceives the world, preferring to be incorporated in it as a silent voyeur or as a researcher who aims to learn more about subjects, people and how they relate to space (whether physical or psychological).

She has participated in several solo exhibitions both in Portugal and abroad, in countries such as Spain, United Kingdom, Ireland and United States of America, having in 2019 started to explore public art through large-scale murals.
