ONE is a global campaigning and advocacy organization supported by millions of members from around the world who are committed to the fight against extreme poverty and preventable disease, particularly in Africa. We hold world leaders to account for the promises made to the poorest, and we press them to support better policies and aid that is more effective. We also work with leaders in Africa to support greater democracy, accountability and transparency and advocate for increased domestic investments in development so that these resources can be effectively deployed. With HQ in Washington, DC, we operate from North America, Europe and Africa.
