Mozarabic chant is the liturgical plainchant repertory of the Visigothic/Mozarabic rite of the Catholic Church, related to the Gregorian chant. It is primarily associated with Hispania under Visigothic rule and later with the Mozarabs and was replaced by the chant of the Roman rite following the Christian Reconquest of the Iberian Peninsula. Although its original medieval form is largely lost, a few chants have survived with readable musical notation, and the chanted rite was later revived in altered form and continues to be used in a few isolated locations in Spain, primarily in Toledo.

The Mozarabic Rite, officially called the Hispanic Rite, and in the past also called the Visigothic Rite, is a liturgical rite of the Latin Church once used generally in the Iberian Peninsula (Hispania), in what is now Spain and Portugal. While the liturgy is often called 'Mozarabic' after the Christian communities that lived under Muslim rulers in Al-Andalus that preserved its use, the rite itself developed before and during the Visigothic period. After experiencing a period of decline during the Reconquista, when it was superseded by the Roman Rite in the Christian states of Iberia as part of a wider programme of liturgical standardization within the Catholic Church, efforts were taken in the 16th century to revive the rite and ensure its continued presence in the city of Toledo, where it is still celebrated today. It is also celebrated on a more widespread basis throughout Spain and, by special dispensation, in other countries, though only on special occasions.
