Helene Lange (April 9, 1848, Oldenburg - May 13, 1930, Berlin) was a pedagogue and feminist, and a symbol of the Women's Movement in Germany.
She took her teacher's exam in 1871, and was active as a house teacher. By 1876, she was a teacher and chief of seminar for the Crain Institute, a girls' school in Berlin. In 1887, Lange published a petition that criticized the way women were taught in schools.
