Servant of God is a title given to individuals by different religions, but in general the phrase is used to describe a person believed to be pious in his or her faith tradition. In the Catholic Church, it designates someone who is being investigated by the Church for possibly being recognized as a saint. In the Eastern Orthodox churches, this term is used to refer to any Eastern Orthodox Christian.

The Arabic name Abdullah عبد الله, the Hebrew name Obadiah עובדיה and the German name Gottschalk literally mean "servant of God".
