"The Foo Fighters family is devastated by the tragic and untimely loss of our beloved Taylor Hawkins," their message said.
"His musical spirit and infectious laughter will live on with all of us forever. Our hearts go out to his wife, children and family."
According to local media, Hawkins was found in a hotel room in Bogota, Colombia, where the Foo Fighters were due to play at the Festival Estéreo Picnic.
The festival confirmed the band had cancelled its performance following the shock death.
