Hanging of the Greens is a traditional Christian ceremony of decorating the church for the Advent and Christmas season, often celebrated on the first Sunday of Advent or during a separate evening service.

Some churches have a Hanging of the Greens service on a Sunday afternoon, the week before the first Sunday of Advent. Others have a workshop-style event the day before the first Sunday of Advent, where families come and learn about the significance of our Christmas decorations and help prepare the church for the new season.
