“867-5309/Jenny” is a 1981 song written by Alex Call and Jim Keller and performed by Tommy Tutone that was released on the album Tommy Tutone 2, on the Columbia Records label. It peaked at No. 4 on the Billboard Hot 100 chart in May 1982, and No. 1 on the Billboard Hot Mainstream Rock Tracks chart in April 1982.

On March 28, 2008, Tommy Tutone lead singer Tommy Heath stated on the WGN Morning News that the number was real and it was the number of a girl he knew. As a joke, he wrote it on a bathroom wall in a motel where they were staying. "We laughed about it for years," he said. 
The song led to a fad of people dialing 867-5309 and asking for “Jenny”.
