Hilda Sjölin (1835–1915), was a Swedish photographer, likely the first professional woman pioneer photographer in her country.
Sjölin was raised in Malmö as one of four daughters. On 24 May 1860 she advertised in Malmö that she performed photography on glass, waxcanvas and paper, and by February 1861, she opened her own studio on Västergatan, in the house where she was raised. She was soon the "competent rival" of the other photographer of the city, C. M. Tillberg, and no longer had to advertise. She was known for her card - and portrait photography, and was from 1864 also employed as a photographer of the city views, and she was the first photographer to take stereographic images of Malmö. She seems to have been no longer active after 1870. She left Malmö in 1884, and moved to Hörby with her likewise unmarried sister in 1910.
