The Patriarchal cross is a variant of the Christian cross, the religious symbol of Christianity, and is also known as the Cross of Lorraine. Similar to the familiar Latin cross, the patriarchal cross possesses a smaller crossbar placed above the main one so that both crossbars are near the top. Sometimes the patriarchal cross has a short, slanted crosspiece near its foot. This slanted, lower crosspiece often appears in Byzantine Greek and Eastern European iconography, as well as in other Eastern Orthodox churches. In most renditions of the Cross of Lorraine, the horizontal bars are "graded" with the upper bar being the shorter, though variations with the bars of equal length are also seen.

The Christian cross, seen as a representation of the crucifixion of Jesus on a large wooden cross, is a symbol of Christianity. It is related to the crucifix and to the more general family of cross symbols, the term cross itself being detached from the original specifically Christian meaning in modern English.
