A Christmas market is a street market associated with the celebration of Christmas during the four weeks of Advent. These markets originated in Germany, but are now held in many countries. Some in the U.S. have adapted the name to the quasi-German Christkindlmarket, substituting market for German Markt.

Advent is a season observed in most Christian denominations as a time of expectant waiting and preparation for both the celebration of the Nativity of Christ at Christmas and the return of Christ at the Second Coming. Advent is the beginning of the liturgical year in Western Christianity. The name was adopted from Latin adventus "coming; arrival", translating Greek parousia from the New Testament, originally referring to the Second Coming.
