Omatjette (also: Omatjete) is a village in the Erongo Region of Namibia, situated on the road D2344 from Omaruru to Khorixas.

Omatjette has approximately 12,000 residents, many of them living there only temporarily.

[1] The village name was originally Omatjate (Otjiherero: tasty water), referring to a fountain that today is on the western edge of the settlement.

The water-related name of the settlement and surrounding geographical features stems from the scarcity and value of water in this semi-arid terrain; the Omatjette area only receives about 400mm of annual rain.

The village is not connected to Namibia's water network.
