Don Baltasar de Marradas et Vique or Maradas (28 November 1560 – 12 August 1638) was a Spanish nobleman and imperial field marshal during the Thirty Years' War, as well as the governor of Bohemia.

He was the son of Gaspar de Marradas Soler (d. 1569), Baron of Sallent, and the Viceroy of Mallorca (1548–1557), and Anna vich Manrique.

Both came from large noble families who had performed important services to the king as admirals, ambassadors, generals, and prelates.

Marradas, a knight of Malta, arrived at the imperial court of Rudolf II in 1599, in the midst of the Long Turkish War.

Despite the fact that he could show no great military successes, he was raised in 1621 to the rank of an imperial count and provided with plenty of land.
