The speech is scheduled for 10 a.m. that day, Morawiecki told reporters after talks with lower-house Speaker Szymon Hołownia on Wednesday.
The announcement comes after Morawiecki's new Cabinet was sworn into office on Monday following parliamentary elections last month.
Morawiecki's policy speech is expected to highlight the achievements of his previous Cabinets and outline the priorities of the new government, which needs to win a vote of confidence in parliament to remain in office.
Morawiecki has led Poland’s conservative government since 2017. His new Cabinet includes some of his previous ministers, but also many new faces.
Poland's conservative leader Jarosław Kaczyński has said that the new government unveiled on Monday will work as a "team of experts" focused on "policy issues."
Polish voters elected a new set of 460 MPs and 100 senators when they went to the ballot box last month.
Morawiecki's conservative Law and Justice (PiS) party won Poland's October 15 election, but lost its parliamentary majority and looks unlikely to stay in power for a third consecutive term.
A bloc of pro-EU opposition parties in mid-November secured a resounding victory in Poland's new parliament during its first key vote to elect a house Speaker.
Poland's opposition groups have signed an agreement to form a coalition government, pledging to restore the rule of law, promote green energy and relax abortion rules, among other policies.
Opposition leader Donald Tusk, a former top EU official, has already chosen most candidates for ministerial roles in his future Cabinet, according to the Rzeczpospolita newspaper.
Hołownia told reporters last Friday that "all the names of the members of Donald Tusk's future government have been agreed on."
Tusk was Poland's prime minister from 2007 to 2014.
