South Sudan is no longer classified as being in famine following an increase in aid, a UN-backed report says.
However, the report warns that the situation remains desperate as the number of people at risk of starvation has increased in the last month.
The famine, announced in February, was the first be declared anywhere in the world since 2011.
Armed conflict, low harvests and soaring food prices have been blamed for the situation.
Tens of thousands of people have died and millions displaced since fighting erupted in the country more than three years ago.
The Integrated Food Security Phase Classification (IPC) report says that 1.7 million people are still facing emergency levels of hunger, one step below famine.
The IPC adds that the number at risk of starvation has increased to six million, up from 5.5 million last month.
"I do urge caution, as this does not mean we have turned the corner on averting famine," UN humanitarian chief Stephen O'Brien told a meeting in Geneva.
"Across South Sudan, more people are on the brink of famine today than were in February."
The United Nations says the world is facing its biggest humanitarian crisis since the end of World War Two, with a total of nearly 20 million people facing starvation in north-east Nigeria, Somalia and Yemen, as well as South Sudan.
