The Dominican Rite is the unique rite of the Dominican Order of the Roman Catholic Church. It has been classified differently by different sources - some consider it a usage of the Roman Rite, others a variant of the Gallican Rite, and still others a form of the Roman Rite into which Gallican elements were inserted.
The Dominican Order composed and adopted this rite in the mid-thirteenth century as its specific rite. In 1968, it decided to adopt the renewed Roman Rite of Mass and of the Divine Office, as soon as the texts revised after the Second Vatican Council appeared, but it has kept other elements of its proper rite, such as the Rite of Profession.
As a result, the Dominican Rite of the Mass ceased being celebrated after the renewed Roman Rite was promulgated. However, in recent decades it has been celebrated occasionally in some provinces of the Dominican Order. In addition, it is celebrated by the Traditionalist Roman Catholic Dominican Fraternity of St. Vincent Ferrer.
The question of a special unified rite for the order received no official attention in the time of St. Dominic, each province sharing in the general liturgical diversities prevalent throughout the Church at the order's confirmation in 1216. Hence, each province and often each convent had certain peculiarities in the text and in the ceremonies of the Mass and the recitation of the Divine Office. The successors of St. Dominic were quick to recognize the impracticability of such conditions, and soon busied themselves in an effort to eliminate the distinctions. They maintained that the safety of a basic principle of community life—unity of prayer and worship—was endangered by this conformity with different local diocesan conditions. This belief was impressed upon them more forcibly by the confusion that these liturgical diversities occasioned at the general chapters of the order, where brothers from every province were assembled.
