She had already postponed five shows under doctor's orders, but while resting in Los Angeles she saw a specialist "who determined it was imperative that she take the next few weeks to recover with absolute voice rest."
The 23-year-old, known for powerful love songs including "Someone Like You," had been due to resume the sold-out tour in San Francisco on Saturday, but has now canceled the remaining nine dates.
"I'm really frustrated. I was hoping with a weeks rest I'd be better to sing again straight away. However, there is absolutely nothing I can do but take the doctors advice and rest some more," she said in a statement on her website.
"I'm so sorry. See you soon, love Adele."
Adele said plans to reschedule the canceled dates were being considered, and more information would be given when available. (AFP)
