Two Journalists Maria Ressa and Dmitry Muratov have won the Nobel Peace Prize for their "courageous fight" to defend freedom of expression in the Philippines and Russia.
The committee called the pair "representatives of all journalists who stand up for this ideal".
The winners of the prestigious prize, worth 10m Swedish krona (£836,000; $1.1m), were announced at the Norwegian Nobel Institute in Oslo.
They were chosen out of 329 candidates.
Ressa, who co-founded the news site Rappler, was commended for using freedom of expression to "expose abuse of power, use of violence and growing authoritarianism in her native country, the Philippines".
In a live broadcast by Rappler, Ressa said she was "in shock".
She said her win showed that "nothing is possible without facts... a world without facts means a world without truth and trust".
The committee said Muratov, the co-founder and editor of independent newspaper Novaja Gazeta, had for decades defended freedom of speech in Russia under increasingly challenging conditions.
In an interview with the popular Telegram channel Podyom, Mr Muratov said: "I'm laughing. I didn't expect this at all. It's madness here."
He called the prize "retribution for Russian journalism which is being repressed now".
The editor was congratulated by Kremlin spokesman, Dmitry Peskov, who said: "He persistently works in accordance with his own ideals, he is devoted to them, he is talented, he is brave."
The Nobel Peace Prize is intended to honour an individual or organisation that has "done the most or the best work for fraternity between nations".
"Free, independent and fact-based journalism serves to protect against abuse of power, lies and war propaganda," the committee said in a statement.
"Without freedom of expression and freedom of the press, it will be difficult to successfully promote fraternity between nations, disarmament and a better world order to succeed in our time," it added.
Last year's winner was the United Nations World Food Programme (WFP), which was awarded for its efforts to combat hunger and improve conditions for peace.
