Aleksander Koniecpolski (1555–1609[1]) was a voivode (palatine) of Sieradz, a staunch supporter of king Sigismund III Vasa of the House of Vasa.
He was the son of Stanisław Przedbór Koniecpolski and Elżbieta Ligzianka (relative of hetman Jan Tarnowski)[2].
His wife was Anna Sroczycka, daughter of Stanisław Sroczycki, voivode of Kamieniec.
This marriage brought into the Koniecpolscy family large estates at Podolia.
