The Utrecht Psalter is a ninth-century illuminated psalter which is a key masterpiece of Carolingian art; it is probably the most valuable manuscript in the Netherlands. It is famous for its 166 lively pen illustrations, with one accompanying each psalm and the other texts in the manuscript. The precise purpose of these illustrations, and the extent of their dependence on earlier models, have been matters of art-historical controversy. The psalter spent the period between about 1000 to 1640 in England, where it had a profound influence on Anglo-Saxon art, giving rise to what is known as the "Utrecht style". It was copied at least three times in the Middle Ages. A complete facsimile edition of the psalter was made in 1875, and another in 1984 (Graz).

A psalter is a volume containing the Book of Psalms, often with other devotional material bound in as well, such as a liturgical calendar and litany of the Saints. Until the emergence of the book of hours in the Late Middle Ages, psalters were the books most widely owned by wealthy lay persons. They were commonly used for learning to read. Many Psalters were richly illuminated, and they include some of the most spectacular surviving examples of medieval book art.
