Common Worship is the name given to the series of services authorised by the General Synod of the Church of England and launched on the first Sunday of Advent in 2000. It represents the most recent stage of development of the Liturgical Movement within the Church and is the successor to the Alternative Service Book (ASB) of 1980. Like the ASB, it is an alternative to the 1662 Book of Common Prayer (BCP), which remains officially the normative liturgy of the Church of England.

The Alternative Service Book 1980 (ASB) was the first complete prayer book produced by the Church of England since 1662. Its name derives from the fact that it was proposed not as a replacement for the 1662 Book of Common Prayer (BCP) but merely as an alternative to it. In practice, it was so popular that the various printers had to produce several editions very quickly and churches which retained the BCP drew attention to this fact as something to be noted. The Prayer Book Society soon complained that it was becoming hard to find a church which used the old prayer book and that theological colleges were not introducing students to it. It has now been replaced by Common Worship.
