The United States has urged all Ukrainians to cast ballots, including those in rebel-controlled areas in Donetsk and Luhansk in the east, where pro-Russian rebels are vowing to hold their own seperate elections in November.
Voting will not take place in 14 districts of eastern Ukraine currently under the control of the separatists.
President Vladimir Putin's chief of staff, Sergei Ivanov, has said Russia will recognize the election results, telling the Interfax news agency that Russia wants normality to return to Ukraine.
But Ukrainian Prime Minister Arseniy Yatsenyuk has voiced fears the Kremlin could try to disrupt the vote.
