Early Modern English (sometimes abbreviated EModE or EMnE), also known as Early New English (ENE), and colloquially Shakespeare's English, Shakespearean English, or King James' English, is the stage of the English language from the beginning of the Tudor period to the English Interregnum and Restoration, or from the transition from Middle English, in the late 15th century, to the transition to Modern English, in the mid-to-late 17th century. Early Modern English was spoken with Original Pronunciation.

Before and after the accession of James I to the English throne in 1603, the emerging English standard began to influence the spoken and written Middle Scots of Scotland.

The grammatical and orthographical conventions of literary English in the late 16th century and the 17th century are still very influential on modern Standard English. Most modern readers of English can understand texts written in the late phase of Early Modern English, such as the King James Bible and the works of William Shakespeare, and they have greatly influenced Modern English.

Texts from the earlier phase of Early Modern English, such as the late-15th-century Le Morte d'Arthur (1485) and the mid-16th-century Gorboduc (1561), may present more difficulties but are still closer to Modern English grammar, lexicon and phonology than are 14th-century Middle English texts, such as the works of Geoffrey Chaucer.

The change from Middle English to Early Modern English affected much more than just vocabulary and pronunciation.

Middle English underwent significant change over time and contained large dialectical variations. Early Modern English, on the other hand, became more standardised and developed an established canon of literature that survives today.

The English Civil War and the Interregnum were times of social and political upheaval and instability. The dates for Restoration literature are a matter of convention and differ markedly from genre to genre. In drama, the "Restoration" may last until 1700, but in poetry, it may last only until 1666, the annus mirabilis (year of wonders), and in prose lasts until 1688. With the increasing tensions over succession and the corresponding rise in journalism and periodicals, or until possibly 1700, when those periodicals grew more stabilised.

The 17th-century port towns and their forms of speech gained influence over the old county towns. From around the 1690s onwards, England experienced a new period of internal peace and relative stability, which encouraged the arts including literature.
