A Christmas market, also known as Christkindlmarkt (literally: Christ Child Market, but the term "Christkind" usually refers to an angel-like "spirit of Christmas" rather than literally the Christ Child), Christkindlesmarkt, Christkindlimarkt, and Weihnachtsmarkt, 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, naively substituting market for German Markt.

Christmas markets date to the Late Middle Ages in the German-speaking part of Europe and in many parts of the former Holy Roman Empire that included many eastern regions of France. They became a popular Advent custom during the Reformation era. Dresden's Striezelmarkt was first held in 1434 and one of the first true Christmas markets; earlier markets of the season were "December markets". Early mentions of these "December markets" can be found in Vienna (1298), Munich (1310), Bautzen (1384), and Frankfurt (1393).

In many towns in Germany, Switzerland, and Austria, Advent is usually ushered in with the opening of the Christmas market or "Weihnachtsmarkt". In southern Germany, Switzerland and Austria, it is called a "Christkind(e)l(s)(i)markt" (German language, literally meaning "Christ child market"). Traditionally held in the town square, the market offers food, drinks and seasonal items for sale from open-air stalls, accompanied by traditional singing and dancing. On opening night at the Christkindlesmarkt in Nuremberg, and in some other towns, onlookers welcome the "Christkind" (originally boy Jesus, but often depicted as an angel-like girl), acted by a local child.
