The list of those seeking European Parliament seats includes 146 Polish MPs and eight senators, state news agency PAP has reported.
Four lawmakers who were until recently ministers in Poland's pro-EU coalition government are setting their sights on being elected as Euro-MPs, alongside a host of other prominent Euro-enthusiasts.
The Eurosceptic opposition is also fielding many well-known politicians who served as ministers and deputy ministers in Poland's previous conservative government.
Political parties across the spectrum have urged Poles to vote in the upcoming ballot, seen as one of the most important in Europe in decades.
Poland’s elections to the European Parliament will take place on June 9, under a decision signed by President Andrzej Duda.
The elections will provide the country's pro-European Civic Coalition (KO) with another opportunity to consolidate its political support after it failed to defeat the Eurosceptic conservative Law and Justice (PiS) party in local elections in April, the Reuters news agency has reported.
Prime Minister Donald Tusk told his party in April that this year's elections to the European Parliament "are one of the most important in the postwar history of Poland."
"They have never been so important and never had such a radical impact on our everyday lives as they do now, during the war, amid threats that Europe could not even imagine just a few years ago," Tusk said at the time.
He added: "Today, the European Union needs tough realism and defence of Polish interests by people who are credible and believe in Europe."
Around the EU, voting to select a new batch of MEPs will take place between June 6 and 9.
The ballot will be the third in an electoral marathon in Poland, following national parliamentary elections last autumn and local elections in April.
The European Parliament is the directly elected parliamentary institution of the European Union, of which Poland has been a member since 2004.
Poles will go to the ballot box on Sunday to elect 53 MEPs.
Poland became a member of the EU on May 1, 2004, a historic step that underlined the country’s realignment with the West after decades of communist rule.
