苦艾酒（英语：Absinthe 英语发音：/ˈæbsɪnθ/ AB-sinth 或 英语发音：/ˈæbsænθ/ AB-santh; 法语：Absinthe: [absɛ̃t]），历史上描述为蒸馏的，高酒精度数（45-74％ABV，酒精纯度90-148）的一种饮料。它是一种茴香味的烈酒，从植物性药材中萃取，其中包括苦艾（Artemisia Absinthium，又名“大艾草”Grand Wormwood）的花和叶，绿茴芹（green anise），甜茴香（sweet fennel），和其他药材和食用香草。苦艾酒本来是透明无色的，当人们自古就喜欢给它注入植物的天然绿色。历史文献中通常称苦艾酒为la muse（缪斯）和“法语：la fée verte”（绿妖精、绿精灵、绿仙子）。虽然有时它被误作为利口酒的一种，传统上苦艾酒瓶装时是不加糖的，因此，将其归类为烈酒。传统瓶装的苦艾酒酒精度数很高，但饮用前通常使用水进行稀释。

Absinthe (/ˈæbsɪnθ/ or /ˈæbsænθ/; French: [apsɛ̃t]) is historically described as a distilled, highly alcoholic (45–74% ABV / 90–148 U.S. proof) beverage. It is an anise-flavoured spirit derived from botanicals, including the flowers and leaves of Artemisia absinthium ("grand wormwood"), together with green anise, sweet fennel, and other medicinal and culinary herbs. Absinthe traditionally has a natural green colour but may also be colourless. It is commonly referred to in historical literature as "la fée verte" (the green fairy). Although it is sometimes mistakenly referred to as a liqueur, absinthe is not traditionally bottled with added sugar; it is therefore classified as a spirit. Absinthe is traditionally bottled at a high level of alcohol by volume, but it is normally diluted with water prior to being consumed.
