Singapore's Civil Aviation Authority (CAAS) has temporarily suspended the Boeing 737 Max fleet of aircraft from flying into and out of the country.
The decision comes after an Ethiopian Airlines Boeing Max 8 crashed on Sunday, killing 157 people on board.
It was the second fatal accident involving that model in less than five months.
Singapore's Changi Airport is the world's sixth busiest and a major hub connecting Asia to Europe and the US.
But only a handful of airlines operate Max aircraft in and out of the country.
Several airlines and regulators around the world have already grounded the Max 8 model following the crash.
Singapore is believed to be the first country to ban all variants of the Max fleet of aircraft. The suspension went into effect from 14:00 local time (06:00 GMT).
