Global Health Caucus is an umbrella organisation that brings parliamentarians together to advance health priorities and turn global commitments into national action. It connects existing parliamentary networks and helps establish new ones, creating a shared platform for political leadership, collaboration and accountability.

The organisation works to raise the profile of global health issues in national parliaments, encourage cross-party cooperation and regional knowledge sharing, and translate agreed targets into appropriate policies and funding. Its approach includes cultivating parliamentary leaders, mobilising peers and civil society partners, and supporting collaboration with Health and Finance committees that can hold governments accountable. Decentralised regional managers provide timely, practical support to help parliamentarians make an impact in their own settings.

Global Health Caucus also brings parliamentarians together to influence multilateral policy positions and advocate for sustainable health funding. Its Global TB Caucus platform was recognised by the United Nations General Assembly for its work around the 2018 High-Level Meeting on Tuberculosis.
