Gitta Jønsson (5 October 1869 – 6 March 1950) was a Norwegian Labour Party politician and proponent for women's rights.
Jønsson was born in Tromsøysund Municipality, a daughter of Johan Widding Larsen Hagerup and Eline Marie Moe.
As a young woman she worked as housemaid in Tromsø and Kristiania, and was eventually running a milk shop along with her sister.
She married saddle maker Anders Jønsson in 1903, and they settled in Tromsø, where he established a workshop and she opened a café.
She was a member of the board of the Norwegian Labour Party from 1923 to 1945, and chaired the Northern Troms chapter for many years.
