Sarah Affonso, the art name used by Sara Sancha Afonso, (1899–1983) was a Portuguese artist and illustrator who was brought up in the Minho Region in the north of the country.

Adopting a modernist style, she painted scenes of rural life in her childhood province and portraits of peasant women.

After a well-received solo exhibition at the Salon Bobonne in 1928, she returned to Paris where she earned a living sewing clothes.

After continuing painting scenes from Minho in the early years of her marriage, she spent most of her time raising a family.
