Philadelphus coronarius (sweet mock-orange, English dogwood) is a species of flowering plant in the family Hydrangaceae, native to Southern Europe. It is a deciduous shrub growing to tall by wide, with toothed leaves and bowl-shaped white flowers with prominent stamens. In the species the blooms are abundant and very fragrant, but less so in the cultivars. It may resemble, but is not related to varieties of the similarly named dogwood, which is the common name for Cornus in the family Cornaceae.

The specific epithet coronarius means "used for garlands".
