Tenebrae (/ˈtɛ.nə.breɪ/ or /ˈtɛ.nə.bri/—Latin for “darkness”) was a religious service of Western Christianity consisting of and matins and lauds of the last three days of Holy Week (Maundy Thursday, Good Friday, and Holy Saturday) celebrated on the evening of the previous day to the accompaniment of the gradual extinguishing of candles.

In the 21st century, the term is in practice applied also to a Holy Week evening service other than of matins and lauds accompanied by gradual extinguishing of candles or even to a service at other times of day commemorating the Passion of Jesus. In the Roman rite of the Catholic Church, Tenebrae was celebrated in all churches with a sufficient number of clergy until the liturgical reforms of Pope Pius XII in the 1950s. Tenebrae liturgical celebrations also exist in Anglicanism, Protestantism, and Western Rite Orthodoxy.
