Wolfert VI of Borselen (c. 1430 – 29 April 1486, Saint-Omer) was stadtholder of Holland, Friesland, and Zeeland, Admiral of the Netherlands outside Flanders, and Lord of Veere.

Wolfert's sister Margaret married the influential Louis de Gruuthuse.

[6] In 1461 Wolfert accompanied Philip the good to the crowning of King Louis XI in Rheims.

[8] Wolfert then fought alongside his father in the Wars of Liège, notable after the conquest of Dinant in the 1467 Battle of Brustem.

[5] In 1470 Wolfert van Borselen Count of Buchan, lord of Heimsrode, Avoué of Mons (a kind of legal representative) took possession of the Lordship of Fallais.

[10] In 1474 Henry II van Borselen died, and Wolfert took up all his father's titles.

[5] In 1477 Wolfert became stadtholder of Holland, Zeeland and Friesland in place of his brother in law Louis de Gruuthuse, who had to step down for not being a national of those lands.

[11] However, the internal strife (or rebellion against central authority) of the late Hook and Cod wars was very strong , and Wolfert could not, or did not know how to restore order.

[12] In January 1483, the states of Flanders then forced Maximilian to accept a tutelage council to assist him.

Members were Adolph of Cleves, Lord of Ravenstein, Louis de Gruuthuse, Philip of Burgundy-Beveren, Adrien Vilain.

The Order would prolong the process after Wolfert's death, but in the end it decided to abort it.

On 4 July 1485 the marriage contract between Wolfert's daughter Anna (c. 1472 – 1518) and Philip of Burgundy-Beveren (c. 1450 – 1498) was signed.
