The peach-throated monitor (Varanus jobiensis ), also known commonly as the Sepik monitor, is a species of monitor lizard in the family Varanidae. The species is native to New Guinea.
The specific name, jobiensis, which is Latin, means "from Jobi". Jobi is the island also known as Yapen, which is the type locality of this species.
The junior synonym, Varanus karlschmidti, was named in honor of American herpetologist Karl Patterson Schmidt.
Varanus jobiensis grows up to 120 centimetres (3.9 ft) in total length (including tail). The colour of the throat is white-yellow to red, to which one of its common names refers.
Varanus jobiensis is endemic to New Guinea and surrounding islands such as Biak, Salawati, Yapen, Normanby, and Waigeo. It occurs in rainforests at altitudes of 0–900 m (0–2,953 ft).
Varanus jobiensis primarily eats insects, and sometimes frogs, but may also take freshwater fish and small mammals.
Varanus jobiensis is oviparous.
