Friends and allies of Russian President Vladimir Putin were quick to congratulate him on his election win but Western leaders denounced what they called an illegal election.
Here is a round-up of the main reactions so far:
- Chinese President Xi Jinping sent a congratulatory message to Vladimir Putin on Monday, telling his Russian counterpart his re-election "fully reflects the support of the Russian people", Beijing's state media reported.
"Your re-election fully reflects the support of the Russian people for you," Xi told Putin, according to state broadcaster CCTV.
"In recent years, the Russian people have united as one to overcome challenges and move forward steadily on the road to national development and revitalisation," Xi reportedly said.
"I believe that under your leadership, Russia will be able to achieve greater achievements in national development and construction," he said.
"China attaches great importance to the development of China-Russia relations and is willing to maintain close communication with Russia to promote the sustained, healthy, stable and in-depth development of (bilateral ties)," Xi said.
- Former Russian leader Dmitry Medvedev responded long before the final results were due to be announced, saying on Telegram: "I congratulate Vladimir Putin on his splendid victory in the election".
- Ukraine's President Volodymyr Zelensky dismissed the result as illegitimate. "Everyone in the world understands that this person, like many others throughout history, has become sick with power and will stop at nothing to rule forever," he said.
"There is no evil he would not do to maintain his personal power. And no one in the world would have been safeguarded from this."
"This election has been based on repression and intimidation," EU's Foreign Policy Chief Josep Borrell told journalists in Brussels.
A subsequent joint statement from all 27 European Union countries said Russians had been denied a "real choice" after all candidates opposed to the war in Ukraine were excluded.
The EU condemned the staging of the vote in regions of Ukraine occupied by Moscow and said "it does not and will never recognise either the holding of these so-called 'elections' in the territories of Ukraine or their results".
- The French foreign ministry said Paris "had taken note of the expected outcome" of the three-day polls, which saw Putin obtain a fifth term in the Kremlin.
"The conditions for a free, pluralist and democratic election were not met once again," the French foreign ministry said.
It said the vote took place amid "increasing repression of civil society and all forms of opposition to the regime".
"France salutes the courage of the many Russian citizens who have peacefully demonstrated their opposition to this attack on their fundamental political rights," the ministry said.
- Bosnian Serb leader Milorad Dodik said: "The Serb people welcomed with joy the victory of President Putin for they see in him a great statesman and a friend on whom we can always count and who will watch over our people".
- Venezuelan President Nicolas Maduro said: "Our older brother has triumphed, which bodes well for the world".
- Britain's foreign minister David Cameron said the "illegal" elections featured "a lack of choice for voters and no independent OSCE monitoring", adding: "This is not what free and fair elections look like."
- Italian Foreign Minister Antonio Tajani said the "elections were neither free nor fair".
"We are continuing to work for a just peace that will bring Russia to put an end to the war of aggression against Ukraine, in accordance with international law."
- Czech Foreign Minister Jan Lipavsky called the election a "farce and parody". He said: "This was the Russian presidential election that showed how this regime suppresses civil society, independent media, opposition."
