日本茶道（日语：茶道／さどう、ちゃどう）是日本传统艺道，是将生活消闲活动提升至精神意识层次，成为一种独特传统礼仪，是宣扬文化之媒介。日本茶道是为客人奉茶之事，源自中国。是一种茶敍的仪式，日本人称之为「茶汤」（茶汤、茶の汤），而吃茶的敍会则称为「茶会」（CHAKAI）。和其他东亚茶仪式一样，都是一种以品茶为主而发展出来的特殊文化，但内容和形式则有别。茶道历史可以追溯到13世纪。往中国留学的僧侣，于唐朝把佛教和茶带回东瀛。日本最初是僧侣用茶来集中自己的思想，后来才成为分享茶食的仪式。

现代的茶道，由主人准备茶与点心（和菓子）招待客人，而主人与客人都按照固定的规矩与步骤行事。目前一般的茶会较重视领略其精神，所以现代之茶会或作茶道示范时，大多只进行洞茶之部分，但各项礼仪和步骤仍是非常严谨。除了饮食之外，茶道的精神还延伸到茶室内外的布置；品鉴茶室的书画布置、庭园的园艺及饮茶的陶器都是茶道的重点。

The Japanese tea ceremony, also called the Way of Tea, is a Japanese cultural activity involving the ceremonial preparation and presentation of matcha (抹茶), powdered green tea. In Japanese, it is called chanoyu(茶の汤) or sadō, chadō(茶道). The manner in which it is performed, or the art of its performance, is called (o)temae([お]手前; [お]点前). Zen Buddhism was a primary influence in the development of the Japanese tea ceremony. Much less commonly, Japanese tea ceremony uses leaf tea, primarily sencha, in which case it is known in Japanese as senchadō(煎茶道, the way of sencha) as opposed to chanoyu or chadō; see sencha tea ceremony, below.
