A hymn is a type of song, and partially synonymous with devotional song, specifically written for the purpose of adoration or prayer, and typically addressed to a deity or deities, or to a prominent figure or personification. The word hymn derives from Greek ὕμνος (hymnos), which means "a song of praise". A writer of hymns is known as a hymnist. The singing or composition of hymns is called hymnody. Collections of hymns are known as hymnals or hymn books. Hymns may or may not include instrumental accompaniment. Polyhymnia is the Greco/Roman goddess of hymns.

"Amazing Grace" is a Christian hymn written in 1772 and published in 1779 by English Anglican clergyman and poet John Newton (1725–1807). It is possibly the most sung and most recorded hymn in the world, and especially popular in the United States, where it is used for both religious and secular purposes.
