Nittert Fox, also known as Neithart Fuchs (killed at Foxhol 22 July 1499) was a Saxon knight and military commander. According to his hatchment Fox came from an influential family from Franconia (Germany). As a military commander he became involved in the war between the Vetkopers and Schieringers in Friesland and Groningen. In 1495 he occupied Bolsward and the town of Workum had to pay money to stay save. Later on Fox and his army sought shelter in Sneek. The Schieringers Bokke Harinxma and grietman Louw Donia tried to flee the city, but were imprisoned by Fox. Fox demanded ransom for these two men. The people of Sneek asked the city of Groningen to help out. Fox left the country in May 1496, after the ransom was paid.
