蜜蜂花（学名：Melissa officinalis），又名柠檬香脂草（Lemon balm）、柠檬香草，是唇形科蜜蜂花属的一个种，多年生草本，株高约40-45cm，原产温带的中东地区，随后遍及亚洲及地中海国家。目前广泛植于于欧洲、中亚和北美地区。学名中的Melissa在希腊文中为「蜜蜂」之意。古希腊罗马人认为蜜蜂花为月神与猎神黛安娜之化身，将其视为重要植物，栽培于寺庙周围，吸引蜂群制造蜂蜜，作为糖份来源。

香蜂草常出现于欧美神话及史籍中，著名的西洋药草师 Paracelsus在其药典中即有记述。欧美以蜜蜂花为原料的加尔慕罗水(Carmelite water)，迄今仍为法国人夏日之饮料。在欧美将干燥蜜蜂花叶片煮成之茶饮为著名Melissa Tea，被当作感冒时解热之用品。

Melissa officinalis, known as lemon balm, balm, common balm, or balm mint, is a perennial herbaceous plant in the mint family Lamiaceae, native to south-central Europe, North Africa, the Mediterranean region, and Central Asia.

It grows to 70–150 cm (28–59 in) tall. The leaves have a gentle lemon scent, related to mint. During summer, small white flowers full of nectar appear. It is not to be confused with bee balm (which is genus Monarda). The white flowers attract bees, hence the genus name Melissa (Greek for 'honey bee'). Its flavour comes from citronellal (24%), geranial (16%), linalyl acetate (12%) and caryophyllene (12%).
