Eva Matilda Löwstädt-Åström (5 May 1864 – 5 May 1942) was a Swedish painter and graphic artist.
Her grandfather, Carl Teodor Löwstädt, was also a painter and graphic artist.
Her sister, Hilma Amalia Löwstädt (better known as Emma Chadwick) also became an artist.
After her primary education, she studied at the Kunsthochschule Tekniska Skolan (now known as the Konstfack) from 1885 to 1886.
In the 1890s, she returned to France to visit her sister at the artists' colony in Grez-sur-Loing and would spend much of her life alternating between Stockholm and Paris.
