Wycliffe's Bible is the name now given to a group of Bible translations into Middle English that were made under the direction of John Wycliffe. They appeared over a period from approximately 1382 to 1395.

These Bible translations were the chief inspiration and chief cause of the Lollard movement, a pre-Reformation movement that rejected many of the distinctive teachings of the Roman Catholic Church. In the early Middle Ages, most Western Christian people encountered the Bible only in the form of oral versions of scriptures, verses and homilies in Latin (other sources were mystery plays, usually performed in the vernacular, and popular iconography). 

Though relatively few people could read at this time, Wycliffe's idea was to translate the Bible into the vernacular, saying "it helpeth Christian men to study the Gospel in that tongue in which they know best Christ's sentence".

Although translations of parts of the Bible into Anglo-Saxon existed hundreds of years before Wycliffe's translation, John Wycliffe is credited as being the first translation of the entire Bible (both Old and New Testaments) into English. His translation started a revolution, and enabled ordinary people to finally have access to the Bible in a language they could understand. In fact, so profound was the revolution Wycliffe caused that he is called, "The Morning Star of the Reformation" - in other words, Wycliffe marked the start or dawn of the Reformation, and sparked the events that would soon follow.
