The group, led by Prime Minister Donald Tusk, will review the past year since last October's parliamentary elections and outline its priorities for the coming months, Polish state news agency PAP reported.
Key decisions may also be made on the party's agenda for next year’s presidential election.
During the gathering, the Civic Coalition is also expected to unveil a new long-term migration strategy for the country.
Speaking earlier this week, Tusk said that the strategy would focus on combating illegal immigration and propose a modern migration policy for the European Union in the years ahead.
Meanwhile, Poland’s main opposition party, Law and Justice (PiS), plans to merge with its smaller ally Sovereign Poland, according to news reports.
The merger is expected to be officially announced at a right-wing convention in the south-central town of Przysucha on Saturday.
