Organised by the Singapore Tourism Board, the 'Singapore Roars' party will be held on Wednesday evening at the Merlion Park.
Roaring lions will welcome guests from all over the world to the party.
They will include tour operators, hoteliers and the international media.
They are just 30 of the 118 lions that will be performing on Wednesday's 'Singapore Roars' party.
Some 5,000 people are expected to turn up that night, and everyone will be given a party bag to join in the celebration.
There will also be a spectacular pyrotechnic show.
But not all the action takes place on land - the organisers will be getting guests to make a spectacular entrance by sea.
The evening event is part of the $200 million incentive plan to woo tourists in Singapore.
