护摩（homa），意译为火供，最早来自于婆罗门教的吠陀祭祀，后融入佛教成为修行仪式的一种，目前主要盛行于佛教金刚乘和日本神道教。

护摩源自于吠陀时期印度人的宗教仪式，是以火为天之口，烧供品于火，天食之，再赐人以福。婆罗门教有四十四种的火供方法。

Homa is a Sanskrit word that refers to a ritual, wherein an oblation or any religious offering is made into fire. A Homa is sometimes called a "sacrifice ritual" because the fire destroys the offering, but a Homa is more accurately a "votive ritual". The fire is the agent, and the offerings include those that are material and symbolic such as grains, clarified butter, milk, incense and seeds.
