River Donaghey is a writer and filmmaker based in New York.

River is the host of investigative true crime podcast Good Cult, about his life growing up inside a New Age self-help cult.

River has raced horses in Guatemala as a documentary host, lived like a Founding Father, and exposed an international cult obsessed with channeling Hitler.

He produced “Dirtbags at Dope Lake” for The Opportunist, “Ken Kesey’s Acid Quest” for WNYC, and appeared on All Things Considered and the WGA’s OnWriting Guide to Crafting Scripted Podcasts. River’s experimental audio play RecursiveCast premiered at the 2022 Exponential Festival.

A Japanese fashion magazine once called him a "promising novice." That may have been an insult.
