The incumbent president, Andrzej Duda, will face several contenders, including Malgorzata Kidawa-Blonska from the main opposition grouping Civic Coalition (KO).
Duda, who enjoys a clear lead in the polls, is supported by the ruling party, the conservative Law and Justice (PiS).
Other contenders include Wladyslaw Kosiniak-Kamysz of the conservative-agrarian Polish Coalition, Robert Biedron of the Left, Krzysztof Bosak of the far-right Confederation and Szymon Holownia, an independent candidate.
The Polish president is elected for a five-year term of office. (PAP)
