River Wonders, formerly known as River Safari, is a river-themed zoo and aquarium located in Mandai, Singapore, it forms a part of the Mandai Wildlife Reserve, consisting of the Singapore Zoo, Night Safari and Bird Paradise and the newly opened Rainforest Wild. It is built over 12 hectares (30 acres) and nestled between its two counterparts, the Singapore Zoo and the Night Safari, Singapore. It is the first of its kind in Asia and features freshwater exhibits and a river boat ride as its main highlights. The safari was built at a cost of S$160m, with an expected visitor rate of 820,000 people yearly.

Conceptualisation of such as River Wonders (then known as River Safari) began in early 2007, and its construction was officially announced to the public on 11 February 2009 with an estimated completion date of late 2011. The project began with an estimated budget of S$140 million as well as an annual visitor rate of 750,000. However, after the original announcement in 2009, the budget increased by S$20 million in 2010, due to rising construction costs, to S$160 million. The annual visitor rate also increased to 820,000.

The park is built within the current 89-hectare (220-acre) compound already shared by the Singapore Zoo and Night Safari and occupies 12 hectares (30 acres), making it the smallest of the four parks.

The Giant Panda Forest was opened to the public on 29 November 2012, with a soft opening on 3 April 2013, attracting close to 1,500 visitors. The park was officially opened on 28 February 2014, and it was announced that more than 1.1 million have visited the River Safari since its soft opening in April 2013.

On 13 October 2021, River Safari was renamed to River Wonders.
