Jacob Taets van Amerongen (1542 – 4 December 1612) was a land commander of the Utrecht-based order of Teutonic Knights in what are now the Netherlands.

Both his father and his grandfather, Ernst Taets van Amerongen (died 1565), had served as burgomasters of the city of Utrecht.

[3] Jacob Taets left on 1569 for a pilgrimage to the Holy Land, as his great-uncle Anthonis and great-great-grandfather Ernst (died 1473) had done.

The services were held frequently, followed traditional practices such as foot-washing for the poor on Maundy Thursdays, and were fully attended.

[6] Taets tried to restore the order to its former religious nature, and to confirm the allegiance of the Utrecht bailiwick to the Emperor and the Deutschmeister.

[3] A portrait of Taets van Amerongen appears on the seventh panel of a series held in the Duitse Huis that depicts all the land commanders of the order from 1239.
