NAD(P) transhydrogenase, mitochondrial is an enzyme that in humans is encoded by the NNT gene on chromosome 5.

The NNT gene contains 26 exons and encodes a transhydrogenase protein that is ~109 kDa in molecular weight and is involved in antioxidant defense in the mitochondria. Two alternatively spliced variants, encoding the same protein, have been found for this gene.

The C57BL/6J mouse strain used as an animal model in diabetes research has been shown via QTL analysis to contain mutations in the Nnt gene.
