Key topics include "the prospects for deepening transatlantic relations in an era of global challenges and threats," the enlargement of the European Union, energy security, and the EU's role in the reconstruction of Ukraine, according to the Polish President's Office.
The gathering will be held at Kraków's historic Wawel Castle.
The Arraiolos Group brings together heads of state from EU member countries that have parliamentary rather than presidential models of government, Polish state news agency PAP has reported.
The group is named after the small Portuguese town where the first such meeting took place in 2003.
At last year's summit in the Portuguese city of Porto, Duda and his counterparts from 12 other European nations discussed security, migration and Russia's war against Ukraine, according to reports at the time.
The Polish president said after the summit that "there is no doubt that admitting Ukraine to the European Union and NATO would strengthen the security of our part of Europe."
He added that Ukrainian membership of the EU and NATO "will, in fact, mean a defeat for Russia" in its war against Ukraine.
