Greek Cypriots are voting to choose a president after an election campaign focused on the economy and the divided island's suspended peace process, Aljazeera.com reports.
Polling stations opened at 7am (05:00 GMT) on Sunday and will close at 6pm (16:00 GMT), with a 60-minute break at noon.
Results are expected by 830pm (18:30 GMT).
Some 550,000 people have the right to vote in the poll, which is contested by an all-male line-up of nine presidential hopefuls seeking a fixed five-year term in office.
If, as expected, no candidate wins more than 50 percent of the vote, a runoff will be held between the top two challengers a week from Sunday.
