"Wall of Shame" (German: Schandmauer) is a phrase that is most commonly associated with the Berlin Wall. In this context, the phrase was coined by Willy Brandt, and it was used by the government of West Berlin, and later popularized in the English-speaking world and elsewhere from the beginning of the 1960s. Inspired by its usage in reference to the Berlin Wall, the term has later been used more widely.

For example, the term "Wall of Shame" can be applied to things, including physical barriers (walls, fences, etc.) serving dishonourable or disputed separation purposes (like the Berlin Wall and the American border wall), physical and virtual bulletin boards listing names or images for purposes of shaming, and even lists in print (i.e., walls of text naming people, companies, etc. for the purpose of shaming them, or as record of embarrassment).

Additionally, "Wall of Shame" may be a significant part in the building of a "Hall of Shame", although, more often, a "Wall of Shame" is a monument in its own right (i.e., a wall not having been erected as part of any "Hall of Shame" endeavour). More recently, the term "Wall of Shame" has been used in reference to the Mexico–United States barrier, the Egypt–Gaza barrier and the Israeli West Bank barrier.
