Adriaen van Trappen Banckert (c.1615 – 22 April 1684) was a Dutch admiral. In English literature he is sometimes known as Banckers. His first name is often rendered in the modern spelling Adriaan. Van Trappen was the original family name, but the family was also and better known under the name of Banckert. In the 17th century Netherlands such a situation was solved by combining the two names. Adriaen started his career on the ship of his father, fighting the Dunkirkers. In 1639, at the Battle of the Downs, Adriaen was master on that ship. In 1642 he became a captain himself.
