Jonathan Daniel Donahue (born May 6, 1966 in Kingston, New York) is an American rock musician. He has been an integral member of two of North America's more influential indie/experimental bands of the 1990s; The Flaming Lips and Mercury Rev.
Donahue helped form Mercury Rev, along with vocalist/guitarist David Baker, bassist Dave Fridmann, guitarist and clarinetist Grasshopper (born Sean Mackowiak), rooster-tail bass flutist Suzanne Thorpe, and drummer Jimy Chambers, in the late 1980s as a source to create soundtracks to the members' personal student films. The members were further encouraged to explore their talents by their mentor, minimalist composer and multimedia artist Tony Conrad.
Donahue also doubled as a concert promoter in Buffalo. After billing the Butthole Surfers and their opening act The Flaming Lips, Donahue joined the Flaming Lips around 1989/1990 as their guitar technician. He later joined the band as the full-time lead guitarist and played on the albums In a Priest Driven Ambulance and Hit to Death in the Future Head.
