The 1929 Scottish Prayer Book is an official liturgical book of the Scotland-based Scottish Episcopal Church. The 1929 edition follows from the same tradition of other versions of the Book of Common Prayer used by the churches within the Anglican Communion and Anglicanism generally, with the unique liturgical tradition of Scottish Anglicanism. It contains both the forms of the Eucharistic liturgy and Daily Office, as well as additional public liturgies and personal devotions. The second major revision of the Book of Common Prayer following the full independence of the Scottish Episcopal Church, the 1929 Scottish Prayer Book succeeded the 1912 edition and was intended to serve alongside the Church of England's 1662 prayer book.

The Book of Common Prayer (BCP) is the name given to a number of related prayer books used in the Anglican Communion and by other Christian churches historically related to Anglicanism. The first prayer book, published in 1549 in the reign of King Edward VI of England, was a product of the English Reformation following the break with Rome. The work of 1549 was the first prayer book to include the complete forms of service for daily and Sunday worship in English. It contained Morning Prayer, Evening Prayer, the Litany, and Holy Communion and also the occasional services in full: the orders for Baptism, Confirmation, Marriage, "prayers to be said with the sick", and a funeral service. It also set out in full the "propers" : the introits, collects, and epistle and gospel readings for the Sunday service of Holy Communion. Old Testament and New Testament readings for daily prayer were specified in tabular format as were the Psalms and canticles, mostly biblical, that were provided to be said or sung between the readings.
