Thyrotropin-releasing hormone (TRH) is a hypophysiotropic hormone produced by neurons in the hypothalamus that stimulates the release of thyroid-stimulating hormone (TSH) and prolactin from the anterior pituitary.

TRH has been used clinically for the treatment of spinocerebellar degeneration and disturbance of consciousness in humans.[1] Its pharmaceutical form is called protirelin (INN) (/proʊˈtaɪrɪlɪn/).
