Jablonna Palace (Polish: Pałac w Jabłonnie) - a palace, hotel and publicly accessible park-complex in Jablonna near Warsaw.

In 1774, Bishop Michal Poniatowski, the brother of the King Stanislaw August, commissioned the royal architect, Dominik Merlini, to design a new residence. The construction of a three-building complex was proposed: a one-storey palace, which was intended to be the residence of the owner, was to be situated in the middle and flanked on both sides by separate three-storey pavilions.

A scenic English-style park was developed in the 1770s and 1780s, based on the design of architect Szymon Bogumil Zug. The same architect also constructed a series of pavilions, of which three still remain today: the Orangerie, the Chinese Pavilion, and the Grotto.
