Russian President Vladimir Putin welcomes the "return" of annexed Ukrainian territories to Russia during a concert on the Red Square.
The former spy won more than 87 percent of the vote in the three-day vote, which included voting in parts of Ukraine held by Russian forces.
Moscow presented this weekend's presidential election as proof that Russians have rallied around Putin more than two years after the offensive in Ukraine began.
Putin's victory is expected to further tighten his grip on Russia, where dissent is no longer tolerated amid a rapidly accelerating crackdown.
In power since the last day of 1999, he is poised to become Russia's longest-serving leader in more than two centuries.
"Shoulder to shoulder we will go forward and that will make us stronger... Long live Russia!" Putin told the crowd attending a pop concert marking the 10th anniversary of Russia's annexation of the Crimean Peninsula from Ukraine.
Putin boasted of a new rail link in the areas of Ukraine seized by Russian forces, saying those regions had "declared their desire to return to their homeland.
He appeared at the concert alongside the three candidates who ran against him, after hosting them at a meeting in the Kremlin where they all congratulated him.
Kremlin spokesman Dmitry Peskov said Putin's victory showed Russians had consolidated "around his path", calling it "an extremely perfect result".
All of the 71-year-old president's main opponents are dead, in jail or in exile, and the vote took place a month after Putin's main challenger, Alexei Navalny, died in prison.
Authorities urged Russians to vote out of patriotic duty.
"Vladimir Vladimirovich is the foundation of our country," said 23-year-old Viktoria, an IT employee at a state-owned company, as she headed to the concert in Red Square.
Yelena, a 64-year-old economist, said she was not surprised by the result "because I think every citizen who respects our country voted for Putin." / BGNES
