"As many as 20 million Yemenis are food insecure in the world's worst humanitarian crisis," a joint statement by the UN's Food and Agriculture Organization (FAO), the children's fund UNICEF and the World Food Programmed (WFP) said.
According to the IPC -- whose analysis is necessary to decide whether to declare famine in countries -- the 20 million people facing "severe acute food insecurity" represent 67 percent of Yemen's population.
The world's worst humanitarian crisis spiralled in Yemen after a Saudi-led coalition launched an offensive to support the government against Iran-aligned Huthi rebels in March 2015.
It has killed at least 10,000 people, according to the World Health Organization.
The armed conflict was at the top of a list of the "key drivers of food insecurity", which has been further exacerbated by a protracted economic crisis in the impoverished Arab Peninsula country.
Yemen's finances have been devastated by the conflict, with the World Bank reporting the economy has contracted by around 50 percent since 2015.
Unemployment is running at over 30 percent and inflation is projected at around 42 percent, while the majority of state employees are not paid.
A slide in the value of the riyal also has caused food prices in the famine-threatened country to soar.
"A large proportion of the population, even in more stable areas, cannot access basic food commodities because food prices have jumped by 150 per cent compared to pre-crisis levels," the statement said.
