The Organization for the Prohibition of Chemical Weapons, not Malala Yousafzai, won the Nobel Peace Prize for working to rid Syria of such lethal devices.
The OPCW had not figured prominently in this year's Nobel speculation.
Many thought Malala Yousafzai, the 16-year-old Pakistani girl who was shot in the head by the Taliban last October for advocating education for girls, was a lock.
"She is an outstanding woman and I think she has a bright future and she will probably be a nominee next year or the year after that," the committee told the AP.
He declined to comment on whether Malala had even been considered.
The OPCW, for its part, was formed in 1997 to enforce the Chemical Weapons Convention, the first international treaty to outlaw an entire class of weapons.
Based in The Hague, Netherlands, it has largely worked out of the limelight until this year, when the UN called on it to investigate chemical weapons in Syria.
"The conventions and the work of the OPCW have defined the use of chemical weapons as a taboo under international law," the Nobel committee said.
"Recent events in Syria, where chemical weapons have again been put to use, have underlined the need to enhance the efforts to do away with such weapons."
There was no immediate report on what the organization would do with the $1.2 million prize, which is given out annually and once went to Barack Obama.
As for Malala Yousafzai, she is the target of threats by the Taliban, again (see video above) after miraculously surviving the prior attempt on her life.
