Sundown towns, also known as sunset towns, gray towns, or sundowner towns, are all-white municipalities or neighborhoods in the United States and Canada that were most prevalent before the mid-20th century, which practiced a form of racial segregation by excluding non-whites via some combination of discriminatory local laws, intimidation or violence. The term came into use because of signs that directed "colored people" to leave town by sundown.
