The International Association of National Public Health Institutes is a catalyst for the development and growth of the world's national public health institutes – or NPHIs.

In collaboration with countries and partners, IANPHI works to develop stronger and more coordinated public health systems through the enhancement and establishment of NPHIs. 

IANPHI is also a professional association for NPHI directors, providing a platform for advocacy and collective action in addressing public health challenges and opportunities.
