宗主教十字（英语：Patriarchal cross）是基督宗教符号十字架的一种变体。与拉丁十字基本相似，但上方多了一个小横杠代表着耶稣十字架上的罪状牌。在拜占庭希腊和东欧的十字符号中还会在宗主教十字下方再加一个倾斜的小横杠，这也是东正教常用的符号之一。

The Patriarchal cross is a variant of the Christian cross, the religious symbol of Christianity. 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 (Orthodox cross). This slanted, lower crosspiece often appears in Byzantine Greek and Eastern European iconography, as well as Eastern Orthodox churches.
