A processional cross is a crucifix or cross which is carried in Christian processions. Such crosses have a long history: the Gregorian mission of Saint Augustine of Canterbury to England carried one before them "like a standard", according to Bede. Other sources suggest that all churches were expected to possess one. They became detachable from their staffs, so that the earliest altar crosses were processional crosses placed on a stand at the end of the procession. In large churches the "crux gemmata", or richly jewelled cross in precious metal, was the preferred style. Notable early examples include the Cross of Justin II, Cross of Lothair, and Cross of Cong.

A crucifix is a cross with an image of Jesus on it, as distinct from a bare cross. The representation of Jesus himself on the cross is referred to in English as the corpus. The crucifix emphasizes Jesus' sacrifice, including his death by crucifixion, which Christians believe brought about the redemption of mankind. Most crucifixes portray Jesus on a Latin cross, rather than a Tau cross or a Coptic cross.
