Amalia Euphrosyne Lindegren was a Swedish artist and painter. She was a member of the Royal Swedish Academy of Arts (1856).

Amalia Lindegren was born in Stockholm to Anna Catharina Lindgren (d. 1817), who was married to the caretaker Anders Lindgren. After the death of her mother, she was adopted by the wealthy widow of her alleged biological father, the nobleman Benjamin Sandels. Her position as a child was somewhat humiliating, as a form of charity object for the upper classes, and in her later work, her paintings of sad little girls are believed to be inspired by her childhood.

She displayed an early talent, making and selling drawings in the manner of Maria Röhl: she started to paint in oil in 1839, became a student of Sofia Adlersparre in 1842, and participated in her first exhibition the following year.

In 1846, her drawings were noted by the artist and art teacher Carl Gustaf Qvarnström (1810–1867), who was impressed and, through his connections made her one of the four women accepted as students at the Royal Swedish Academy of Arts in 1849, the other three being Lea Ahlborn, Agnes Börjesson and Jeanette Möller. At the time women could only study at the academy by dispensation, as women students where not formally accepted to study at the same terms as male students at the Academy before 1864. In 1850, she became the first woman student to be given a scholarship by the academy to study art in Paris. In Paris, she was the student of Léon Cogniet and then Ange Tissier; in 1854, she studied at the Alte Pinakothek in Münich, in 1854–55 in Rome, and participated in the World Exhibition of Paris in 1856 before returning to Sweden in 1856. She visited Paris again in 1859.

Amalia Lindegren socialized with famed culture personalities of the era such as Fredrika Bremer, Olof Eneroth, Wendela Hebbe and Sophie Adlersparre, but she was described as a silent and modestly humble introvert, who never married, had any lovers or spoke much at social occasions, who: "lived a retiring life without making a fuss about herself, worked hard and was seldom or never satisfied with what she produced".

She died in Stockholm.
