Water-Ma-Trout is a road and an industrial estate on the northern edge of Helston in west Cornwall, England.
Theories about its name are: That its name started as Cornish dialect English for "wet my throat", here used as a name for a dry field. Earlier: that this name is a corruption of "waterman route", due to it being near the water supply towards one of the sources of the River Cober. That the name derives from a corruption of Welter-ma (from "wheal" and "man") and "Trout", the name of the miner.
Industry A range of industries are based around the estate, such as the scuba gear factory AP Diving and Helston Gunsmiths.
