瓶装水是一包装于瓶子内的饮用水，用于个人使用和零售。 其使用的水可以来自任一地方，包括泉水、井水、纯水、自来水，或甚至有未处理或受污染的水。
Bottled water is drinking water packaged in bottles for personal use and retail. The water used can come from anywhere, including spring water, well water, pure water, tap water, or even untreated or polluted water.
许多国家，尤其是发达国家，有国家标准来规范瓶装水的品质，主要用来确保水品质是否安全及标签是否符合内容物。但在其他许多在发展中国家则很少有这些标准，或没有真正地落实这些标准。
Many countries, especially developed countries, have national standards to regulate the quality of bottled water, mainly to ensure the safety of water quality and whether the label conforms to the content. But in many other developing countries, these standards rarely exist or are not really implemented.
