Feminist science fiction is a subgenre of science fiction (abbreviated "SF") focused on such feminist themes as: gender inequality, sexuality, race, economics, reproduction, and environment. Feminist SF is political because of its tendency to critique the dominant culture. Some of the most notable feminist science fiction works have illustrated these themes using utopias to explore a society in which gender differences or gender power imbalances do not exist, or dystopias to explore worlds in which gender inequalities are intensified, thus asserting a need for feminist work to continue.
Feminist science fiction (SF) distinguishes between female SF authors and feminist SF authors. Both female and feminist SF authors are historically significant to the feminist SF subgenre, as female writers have increased women's visibility and perspectives in SF literary traditions, while the feminist writers have foregrounded political themes and tropes in their works.
