Roosje Vos (15 August 1860 – 22 July 1932) was a Dutch seamstress who became an activist in the push for labor protections of working women. Founding trade unions and editing journals, she advocated for suffrage, women's economic independence and an eight-hour work day. An active member of the socialist party and later the communist party, she ran for election to the Groningen Provincial Council and served from 1919–1927.
