Antoine II of Lalaing (1533–1568), 3rd count of Hoogstraten, was a patron and nobleman of the Southern Netherlands.

He was the son of the second count Philip de Lalaing and his wife Anna of Rennenberg.

He became governor of Mechelen at an early age, and in 1558 he was allowed to receive the Holy Sepulcher Knights to their first chapter.

As a consequence, the Duke of Alba banished him, confiscated his possessions, and deprived him of all his rights and privileges, and his library was moved to Madrid.

In a military manoeuver near Tienen after the Battle of Jodoigne, where the army of William of Orange was forced by the Duke of Alba to retreat over the kleine Gete, he was hit in the foot by a shot from his own gun, and on 11 December 1568 he succumbed to his injuries.
