Light Up Night is a family festival in the city of Pittsburgh, Pennsylvania coinciding with the unofficial start of the Christmas holiday shopping season.

Many retailers in Downtown Pittsburgh remain open late, and street vendors and other concessionaires sell food and give away hot beverages, treats and promotional items.

[1] Light Up Night is also a time for free music, including many choirs, street performers, and even rock concerts, downtown and in Station Square.

With the increasing popularity of the event, The Pittsburgh Downtown Partnership has threatened to sue other communities and organizations that fail to pay a licensing fee for trademark infringement.

[4][5] Each year, the Wintergarden inside PPG Place features a model train, gingerbread houses, and a collection of life-sized Santa Claus figures in traditional dress representing countries around the world.
