Pontifical vestments, also referred to as episcopal vestments or pontificals, are the liturgical vestments worn by bishops in the Catholic, Eastern Orthodox, Oriental Orthodox, Anglican, and some Lutheran churches, in addition to the usual priestly vestments for the celebration of the mass, other sacraments, sacramentals, and canonical hours. The pontifical vestments are only worn when celebrating or presiding over liturgical functions. As such, the garments should not be confused with choir dress, which are worn when attending liturgical functions but not celebrating or presiding.

The chasuble is the outermost liturgical vestment worn by clergy for the celebration of the Eucharist in Western-tradition Christian churches that use full vestments, primarily in Roman Catholic, Anglican, and Lutheran churches. In the Eastern Orthodox Churches and in the Eastern Catholic Churches, the equivalent vestment is the phelonion.
