The Polish president is expected to "discuss economic, humanitarian, political and military support" for the war-torn country, his office said, as Russia's invasion of Ukraine nears the six-month mark.
Duda is also scheduled to take part in talks on international support for Ukraine, according to his chief of staff, Paweł Szrot.
Duda and Zelensky will both attend the Second Summit of the Crimea Platform initiative in the Ukrainian capital on Tuesday, Szrot told reporters.
He declined to provide further details of the visit, citing security concerns, public broadcaster Polish Radio’s IAR news agency reported.
Duda last August attended the first Crimea Platform summit in Kyiv. He said at the time that Poland "will not be indifferent to Russian attempts to harm Ukraine's territorial integrity and to human tragedy unfolding in the Crimean Peninsula."
Russia annexed the Crimea peninsula from Ukraine in 2014 and then fomented a separatist conflict in that country's eastern Donbas region.
Wednesday will mark 31 years since Ukraine regained its independence from the Soviet Union in 1991 and also exactly six months since Russia invaded the country on February 24, 2022.
Duda has met with Zelensky five times this year, including on three visits he has made to Ukraine since the start of the invasion, Polish state news agency PAP reported.
The two previously met in Kyiv in May, April and February, and they also held bilateral talks when Ukraine's Zelensky visited Poland in January.
