Held every four years, the World Public Health Nutrition Congress was established by the World Public Health Nutrition Association (WPHA) to bring together the international public health nutrition sector for an international congress free from funding from conflicted sources. The Congress acts as a pathway to strengthen the knowledge base, partnership and commitment for effective action to improve nutrition related health, particularly vulnerable population around the world.

The Congress was first held in Rio, Brazil in 2012 then Cape Town, South Africa in 2016 and in 2020 the World Public Health Nutrition Congress will be brought to Australia for the first time and hosted by the Public Health Association in Australia (PHAA).
