Paradise Regained is a poem by English poet John Milton, first published in 1671 by John Milton. The volume in which it appeared also contained the poet's closet drama Samson Agonistes. Paradise Regained is connected by name to his earlier and more famous epic poem Paradise Lost, with which it shares similar theological themes; indeed, its title, its use of blank verse, and its progression through Christian history recall the earlier work. However, this effort deals primarily with the temptation of Christ as recounted in the Gospel of Luke.

An interesting anecdote recounted by a Quaker named Thomas Ellwood provides some insight into Paradise Regained's development. After studying Latin with Milton and reading the poet's epic Paradise Lost, Ellwood remarked, "Thou hast said much here of Paradise lost, but what hast thou to say of Paradise found?" Hearing this, Milton at first "sat some time in a muse" before changing the subject; however, sometime thereafter he showed to Ellwood a new manuscript entitled Paradise Regained. Some maintain that although he seemed to express gratitude to Ellwood in a letter, Milton in truth "passed on a friendly if impish fabrication" that made Ellwood feel like the inspiration for the poem. Milton composed Paradise Regained at his cottage in Chalfont St Giles in Buckinghamshire. The poem is four books long, in contrast with Paradise Lost's twelve; 2,065 lines long, while Paradise Lost comprises 10,565. As such, Barbara K. Lewalski has labelled the work a "brief epic".

Whereas Paradise Lost is ornate in style and decorative in its verse, Paradise Regained is carried out in a fairly plain style. Specifically, Milton reduces his use of simile and deploys a simpler syntax in Paradise Regained than he does in Paradise Lost, and this is consistent with Jesus's sublime plainness in his life and teachings (in the epic, he prefers Hebrew psalms to Greek poetry). Modern editors believe the stylistics of Paradise Regained evince Milton's poetic maturity. No longer is the poet out to dazzle his readers with bombastic verse and lengthy epic similes. This is not to say that the poem bears no affinities with Milton's earlier work, but scholars continue to agree with Northrop Frye's suggestion that Paradise Regained is "practically sui generis" in its poetic execution.
