MenEngage is made up of more than 300 Non-Governmental Organizations from around the world. Member organizations can participate in the MenEngage listserv, post information about the NGO's activities, and participate in Country and Regional Networking (when it exists).

NGOs wishing to become members of the MenEngage Alliance are asked to fill out the registration form which will be reviewed by the MenEngage Steering Committee. Your organization’s information will be made available on the MenEngage website and will facilitate networking among organizations. NGOs seeking to become NGO members are also asked to sign a pledge to support the MenEngage Core Principles.
