Varanus reisingeri, known commonly as Reisinger's tree monitor and the Yellow tree monitor, is a species of monitor lizard in the family Varanidae.

It was at one point at least considered an allopatric insular subspecies of the green tree monitor, due to physical and genetic similarities.

[3] The specific name, reisingeri, is in honor of Manfred Reisinger, a German naturalist and reptile breeder.

[4] Varanus reisingeri is found on the island of Misool in West Papua, Indonesia.

[2] The natural habitat of V. reisingeri is forest, from sea level to an altitude of 535 m (1,755 ft).
