A Clergy shirt is an item of clerical clothing worn by some members of the Christian clergy. It is a shirt, usually black, that either is collarless and worn with a detachable clerical collar or has a high banded collar sewn to accommodate a white cloth or soft plastic insert, leaving a small white square at the base of the throat.

Clergy shirts are often worn with a suit of conservative design, often black.

In some Western Christian churches, a bishop will be distinguished by wearing a purple or burgundy clergy shirt when not vested for a service .

In Orthodox Christianity, priests or bishops who wear clergy shirts instead of cassocks are sometimes criticized by traditionalists for modernism.
