The Whole Booke of Psalmes Faithfully Translated into English Metre, commonly called the Bay Psalm Book, is a metrical psalter first printed in 1640 in Cambridge, Massachusetts. It was the first book printed in British North America. The psalms in it are metrical translations into English. The translations are not particularly polished, and none have remained in use, although some of the tunes to which they were sung have survived (for instance, "Old 100th"); however, its production, just 20 years after the Pilgrims' arrival at Plymouth, Massachusetts, represents a considerable achievement. It went through several editions and remained in use for well over a century.

In November 2013, one of eleven known surviving copies of the first edition sold at auction for $14.2 million, a record for a printed book.
