Pál Kitaibel (3 February 1757 – 13 December 1817) was a Hungarian botanist and chemist.
He was born at Nagymarton (today Mattersburg, Austria) and studied botany and chemistry at the University of Buda.
Together with Franz de Paula Adam von Waldstein (1759–1823), he wrote Descriptiones et icones plantarum rariorum Hungariae ("Descriptions and pictures of the rare plants of Hungary"; M. A. Schmidt, Vienna, three volumes, 1802–1812).
In this work he made the first description of Nymphaea lotus var.
The genus Kitaibelia[2] of mallows was named after him by Carl Ludwig von Willdenow.
