PMNCH is the world’s largest alliance working for the health and well-being of women, children and adolescents with more than 1,500 partner organizations across 10 constituencies. Its vision is a world in which every woman, child and adolescent realizes their right to health and well-being, leaving no one behind. Its mission is to mobilize, align and amplify the voices of partners to advocate for vulnerable populations. PMNCH enables members to deliver more collectively than each could deliver alone, across three thematic areas of work: MNCH: preventable maternal and child mortality, including newborn deaths and stillbirths, with a focus on humanitarian and fragile settings; SRHR: advancing progressive SRHR and countering the growing pushback on SRHR; and AWB: advancing the well-being of adolescents. With advocacy as its core function-supported by knowledge synthesis, partner engagement, and campaigns and outreach-PMNCH seeks changes in policy, financing and services for women, children and adolescents, and holds each other accountable for delivering on promises.
