A Shakespeare garden is a themed garden that cultivates plants mentioned in the works of William Shakespeare. In English-speaking countries, particularly the United States, these are often public gardens associated with parks, universities, and Shakespeare festivals. Shakespeare gardens are sites of cultural, educational, and romantic interest and can be locations for outdoor weddings.

Signs near the plants usually provide relevant quotations. A Shakespeare garden usually includes several dozen species, either in herbaceous profusion or in a geometric layout with boxwood dividers. Typical amenities are walkways and benches and a weather-resistant bust of Shakespeare. Shakespeare gardens may accompany reproductions of Elizabethan architecture. Some Shakespeare gardens also grow species typical of the Elizabethan period but not mentioned in Shakespeare's plays or poetry.

Shakespeare is reputed to have been an avid gardener, though his opportunities in London would have been very limited.^{[citation needed]} In January or February 1631 Sir Thomas Temple, 1st Baronet, of Stowe, was eager to send his man for cuttings from the grapevines at New Place, Stratford, the home of Shakespeare's retirement. Temple's surviving letter, however, makes no note of a Shakespeare connection: he knew the goodness of the vines from his sister-in-law, whose house was nearby. The revival of interest in the flowers mentioned in Shakespeare's plays arose with the revival of flower gardening in the United Kingdom. An early document is Paul Jerrard, Flowers from Stratford-on-Avon (London 1852), in which Jerrard attempted to identify Shakespeare's floral references, in a purely literary and botanical exercise, such as those by J. Harvey Bloom (Shakespeare's Garden London:Methuen, 1903) or F.G. Savage, (The Flora and Folk Lore of Shakespeare Cheltenham:E.J. Burrow, 1923). This parallel industry continues today.
