The House of Lanckoroński (plural: Lanckorońscy) was an old Polish aristocratic family.^[1][2] Its representatives held power and influence in the Kingdom of Poland from the times of the late Piast dynasty (14th century) to the end of the Polish–Lithuanian Commonwealth (18th century).

The Lanckoroński name derives from the village of Lanckorona in Lesser Poland, a site of a castle. The family had previously hailed from Brzezie (today part of the town of Wodzisław). The Lanckorońskis were based in Kraków and Sandomierz and used the Zadora coat of arms.

Emperor Joseph II’s confirmed the validity of the title of Count granted to the Lanckoroński family (18 November 1783). In the late 19th century, Count Karol Lanckoroński built the Palais Lanckoroński in Vienna.
