A Hakka walled village is a large multi-family communal living structure that is designed to be easily defensible. This building style is unique to the Hakka people found in southern China. Walled villages are typically designed for defensive purposes and consist of one entrance and no windows at the ground level.

The Hakka, sometimes also referred to as Hakka Han, or Hakka Chinese, or Hakkas, are a Han Chinese subgroup whose ancestral homes are chiefly in the Hakka Chinese-speaking areas of Guangdong, Fujian, Jiangxi, Guangxi, Sichuan, Hunan, Zhejiang, Hainan, and Guizhou in China, as well as in Taoyuan City, Hsinchu County, Miaoli County, Pingtung County, and Kaohsiung City in Taiwan. Unlike other Han Chinese subgroups, the Hakkas are not named after a geographical region, e.g. a province, county or city, in China. That is because their origins were of northern Chinese refugees fleeing social unrest, upheaval and invasions throughout the northern parts of China throughout history who then sought sanctuary in the south where the Cantonese-speaking provinces such as Guangdong and Guangxi are. The Chinese characters for Hakka literally mean "guest families". The word is Cantonese in origin and as the name implies, they are the guest of the Cantonese people. Over the centuries though, they have since more or less assimilated with the Cantonese-speaking population. Modern day Hakka are generally identified by both full Hakka and by different degrees of Hakka ancestry and usually speak Hakka Chinese.
