Christian Cyclopedia (originally Lutheran Cyclopedia) is a one-volume compendium of theological data, ranging from ancient figures to contemporary events. It is published by Concordia Publishing House. It should not be confused with The Lutheran Cyclopedia (New York: Charles Scribners Sons, 1898), edited by Henry Eyster Jacobs and Charles A.W. Haas, of the General Council and its Lutheran Theological Seminary at Philadelphia.
