Bolette Margrethe Gjør, née Nissen (11 May 1835 – 4 November 1909) was a Norwegian writer and inner missionary.
[1] She was born in Trondheim as a daughter of merchant Martinus Nissen (1800–1836) and Ida Susanne Amalie Hagerup (1808–85).
In her early twenties she underwent a Christian awakening in the milieu surrounding Gisle Johnson.
They were not formally connected to the Norwegian Missionary Society (Det Norske Misjonsselskap), where women did not have voting rights, but nonetheless contributed with two thirds of the organization's income.
Gjør gathered support to grant women elective rights in the Norwegian Missionary Society, an endeavor which became successful in 1904.
