菊苣，又称苦苣、苦菜，（学名：Cichorium intybus），是一种灌木丛生的多年生草本植物，长出蓝色或薰衣草色的小花。原生于欧洲，但现时已自然生长于北美等地而成为路边物种。经烘焙及磨碎后的根部广泛用作咖啡代用品起源于地中海，但现在在全球，特别是美国南部的新奥尔良地区、印度及东南亚也广受欢迎。与此同时，它也是制作红眼肉汁的主要材料。 常见的菊苣有多个名称，包括blue sailors、succory、coffeeweed等。中文的称谓繁多，包括野生苔苣、法国苦苣、比利时苦苣等，但其实它们并不指同一品种。

Common chicory, Cichorium intybus, is a somewhat woody, perennial herbaceous plant of the dandelion family, usually with bright blue flowers, rarely white or pink. Many varieties are cultivated for salad leaves, chicons (blanched buds), or roots (var. sativum), which are baked, ground, and used as a coffee substitute and additive. It is also grown as a forage crop for livestock. It lives as a wild plant on roadsides in its native Europe, and now common in North America, China, and Australia, where it has become widely naturalized.
