Gertrud Dahlgren (1931–2009) was a Swedish botanist. She was born at Klippan in Scania, and after graduating from university at Helsingborg went to the University of Lund for graduate studies. There she obtained her M.Sc. in chemistry and biology. She was married to fellow botanist Rolf Dahlgren (1932–1987), who was killed in a car accident. The couple had three children, Susanna, Helena and Fredrik. She died in December 2009 at the age of 78.

At Lund, Gertrud Dahlgren pursued studies in systematic botany. Henning Weimarck, who held the chair in Systematic Botany, had initiated a new line of research in the mid-1950s, the field of biosystematics, which was to become Gertrud Dahlgren's chosen field, and to receive international attention. She achieved her Ph.D. in 1967 for her work on the genus Sanguisorba, and in particular two Swedish species, S. officinalis and S. minor. She was appointed to the position of Associate professor at Lund, and continued her work in biostematics, with especial interest in Ranunculus and Erodium, and editing a textbook on systematic botany, which was later translated into German. In 1979 she was appointed head of the department of Systematic Botany at Lund, a position she held till 1987 when, following the death of her husband, she turned to continuing his work on angiosperm taxonomy. In 1992 she was elected to the Kungliga Fysiografiska Sällskapet i Lund (Royal Physiographic Society in Lund).
