The Verrett River is a tributary to the Iskut River and the Stikine River in British Columbia, Canada. It begins in the Boundary Ranges of the Coast Mountains roughly 40 kilometres (25 mi) from the Alaskan border and flows south until it meets the Iskut River, immediately east of Mount Verrett. It is remote, short, and hardly documented, and is found in an isolated part of the Cassiar Land District, east of Stikine.
