Hilma Margareta Wallin-Kylander (1912–1990) was a Swedish painter whose career reflected both Swedish and international influences. Born in Bringetofta, Jönköping County, she was the daughter of Johan Wallin and Josefina Lagerquist. In 1958 she married Hadar Kylander.

Wallin-Kylander studied with Waldemar Lorentzon in Halmstad (1945–1946) and at the Academy of Fine Arts in Florence (1948). She lived in Paris from 1950 to 1956, where she studied with André Lhote at the Académie Julian, immersing herself in the city’s vibrant postwar art scene.

Following her time in France, she undertook study and painting trips to Spain, Portugal, and Greece, further broadening her stylistic range. Her work reflects a synthesis of Swedish modernism with European influences, particularly Cubism and figurative abstraction.
