The Disasters Emergency Committee has raised £20m for the Yemen Crisis Appeal since it launched on 13 December.
Funds have been raised from the public, corporate supporters, and the Government through its Aid Match contribution, DEC said.
The UN has announced Yemen is on the brink of famine with almost 80 per cent of the population, almost 19 million people, in need of help. DEC said funds raised through its appeal have provided aid to more than 1.5 million people.
DEC brings together 13 UK aid charities in times of crisis: ActionAid UK, Age International, British Red Cross, CAFOD, CARE International UK, Christian Aid, Concern Worldwide, Islamic Relief, Oxfam, Plan International UK, Save the Children, Tearfund, and World Vision.
Saleh Saeed, DEC chief executive, has just returned from Yemen and said the funds raised were already making a huge difference.
“However, the numbers in need were overwhelming,” he said. “Having been born in Yemen, and visited many times over the years, I was truly shocked to see how the country had been devastated by conflict. The lives of so many families are at risk because of the food crisis and we need more funds to prevent Yemen slipping into widespread famine.”
