The Lutheran Book of Worship (LBW) is a worship book and hymnal published in 1978 and was authorized for use by several Lutheran denominations in North America, including predecessors of the Evangelical Lutheran Church in America and Evangelical Lutheran Church in Canada. The Lutheran Church—Missouri Synod was initially involved in the hymnal's development but officially withdrew.
Additional hymns and service music are contained in the companions Hymnal Supplement 1991 and With One Voice (WOV). A successor was published in 2006 titled Evangelical Lutheran Worship, although Lutheran Book of Worship remains in use by some congregations.
