The US pop group - consisting of Kevin, Nick and Joe Jonas - ended speculation about their future today (29 October), explaining that it was an "unanimous decision".
"It's over for now," Kevin told People magazine. "It's really hard to say 'forever'," continued Nick. "We're closing a chapter, for sure."
The pop group have been together since 2005 and gained worldwide popularity when they appeared in Disney film Camp Rock.
Rumours first surfaced that they were heading for a split when they suddenly cancelled a 19-date American tour just two days before it was due to begin.
Earlier this month, Nick and Joe addressed fans, explaining that there was a "deep rift" within the band.
Jonas Brothers have sold more than eight million albums worldwide, and their 2007 single 'SOS' was their most successful UK single, reaching number 13 in the charts.
Eldest Brother Kevin is expecting a baby with his wife Danielle.
