Calw was originally part of the [[Roman Catholic Diocese of Speyer]]. From 1534, in Calw as in the rest of the Duchy of Württemberg, the Reformation took force. In 1555, Calw became the seat of a [[deanery]], which still exists today. The Deanery of Calw encompasses 43 congregations of the [[Evangelical-Lutheran Church in Württemberg]]. In the town of Calw there is the greater congregation of Calw, comprising the town-centre congregation (Calw Stadtkirche), the Bergkirche congregation of Wimberg/Alzenberg, and the Versöhnungskirche congregation of Heumaden, of which the last two came into existence only after the arrival of ''[[Heimatvertriebene]]'' after World War II. There are also congregations in the villages of Altburg, Hirsau, Holzbronn und Stammheim.

There is also a congregation of the [[United Methodist Church]], an independent Protestant church, in Calw.

The parish of St. Josef covers the entire territory of the town as well as several surrounding communities.
