Yuriy Yekhanurov received 289 votes out of 450 in the country's parliament, the Verkhovna Rada.
Before the vote, Yushchenko spoke before the parliament.
"I appeal to you as political leaders, I appeal to civil and business circles -- we must bury the hatchet of war, hide it far under the bench and forget where it is," Yushchenko said.
The vote comes two days after lawmakers rejected Yekhanurov by a narrow margin.
Yekhanurov succeeds Yuliya Tymoshenko, who was sacked two weeks ago amid infighting and accusations of corruption among senior officials.
