This entry provides an overview of activist mothering, a type of activism that develops out of the mothering role. Despite the long history of mothers being active in social movements, and the rapid increase in mothering movements today, this type of activism has a history of being dismissed as just part of a mother's “job.” Recent research has challenged this and has instead established mother‐activism as a powerful and multifaceted type of activism that is launched from the mothering identity. Three frameworks often applied to activist mothering are discussed – liberal feminism, maternalism, and the feminist ethic of care – as well as a new framework, matricentric feminism, which combines these three frameworks. In addition, the manifestations of activist mothers at the local, regional, and global levels on a variety of social issues are described.
