Tryptophan hydroxylase 1 (TPH1) is an isoenzyme of tryptophan hydroxylase which in humans is encoded by the TPH1 gene.

TPH1 was first discovered to support serotonin synthesis in 1988 by converting tryptophan into 5-hydroxytryptophan. It was thought that there only was a single TPH gene until 2003. A second form was found in the mouse (Tph2), rat and human brain (TPH2) and the original TPH was then renamed to TPH1.
