A wreath is an assortment of flowers, leaves, fruits, twigs, or various materials that is constructed to form a circle .

In English-speaking countries, wreaths are used typically as household ornaments, most commonly as an Advent and Christmas decoration. They are also used in ceremonial events in many cultures around the globe. They can be worn as a chaplet around the head, or as a garland around the neck.

In Christianity, wreaths are used to observe the Advent season, in preparation for Christmastide and Epiphanytide, as well as to celebrate the latter two liturgical seasons. These wreaths, as with other Advent and Christmas decorations, are often set up on the first Sunday of Advent, a custom that is sometimes done liturgically, through a hanging of the greens ceremony. The Advent wreath was first used by Lutherans in Germany in the 16th century, and in 1839, Lutheran priest Johann Hinrich Wichern used a wreath made from a cart wheel to educate children about the meaning and purpose of Christmas, as well as to help them count its approach, thus giving rise to the modern version of the Advent wreath.
