Duda's top foreign policy aide, Marcin Przydacz, has told reporters that the meeting will focus on issues including international security and migration policies.
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 reported.
The group is named after the small Portuguese town where the first such meeting took place in 2003.
In October last year, Arraiolos Group leaders held a summit in Valletta, Malta.
