Onverdacht (listenⓘ) is a village in the resort of Zuid in the Para District of Suriname.

[2] In 1939, bauxite was discovered at Onverdacht by the Dutch Billiton company (nowadays part of BHP).

[3] In 1941, a concession was granted to start mining at Onverdacht.

[4] A prefab housing estate was built near the village to accommodate the workers,[5] however Onverdacht remained relatively small due to its proximity to Paramaribo.

[9] In 1993, Billiton signed a joint venture with Suralco (Alcoa), and in 2009 closed their operations in Suriname.
