Jean-Baptiste de Brouchoven (1619—1681) was a holder of high office and a diplomat in the Spanish Netherlands.
In May 1655 he was appointed a member of the Council of Finance, and in 1660 he became a knight in the Order of Santiago. In 1663 he travelled to Madrid to take up an appointment as a councillor of the Supreme Council of Flanders. He successfully appealed to be allowed to retain concurrent membership of the Council of Finance. In 1665 he returned to the Spanish Netherlands as a Councillor of State. He was created baron of Bergeyck in 1666 and count in 1676.
In late 1667 he represented Philip IV of Spain in diplomatic negotiations with the Dutch Republic in The Hague. From late 1674 to early 1675, and again in 1677, he served as the king's acting ambassador to England.
In October 1677 he was reappointed to the Council of Flanders in Madrid.
