Leithaprodersdorf, also (Leitha-Prodersdorf; Croatian: Lajtaproderštof, Hungarian: Lajtapordány, Lajtha-Pordány) is an Austrian town located in the Eisenstadt-Umgebung district of the state of Burgenland.

The town is located on Burgenland's northern border with Lower Austria, near the state capital of Eisenstadt.

Previous archaeological expeditions have noted that the area around Leithaprodersdorf was heavily settled in ancient Roman times.

However, the largest and most visible evidence of the village's early history is the "G'Schlößl," a structure consisting of three concentric rings of walls and ditches, built in the 13th century out of the ruins of the Roman watchtower, and used as a dike to stay protected against flooding of the Leitha River.

The city later belonged to the Austro-Hungarian Empire, and because of its policy of Magyarization, the name of the settlement was changed to Lajtapordány.
