Equites Calicis Argenteae, more commonly called The Knights of the Silver Chalice, is a non-denominational Christian men's organization started in the Seattle, WA area in 1996.

The organization takes the fact that Scripture clearly speaks, in a number of places, in terms of military service. Taking this metaphor, they have used the Medieval Knight as the symbol of the Soldier of Christ; and strive to re-establish the Biblical basis of the Code of Chivalry.
