大壶节（天城体：कुम्भ मेला）是印度教每三年举行一次的宗教活动，每次择一在印度四个城市（安拉阿巴德、赫尔德瓦尔、乌贾恩、纳西克）举行，另外每六年在安拉阿巴德和赫尔德瓦尔举行半礼，每三年一次小礼。举行的日期可以长达五十五天，2013年的一次预计将有一亿人次参加。

决定节日举行的地点依靠太阳和木星的位置：当两个星体出现于狮子宫，节日就在纳西克举行；太阳在白羊宫时就在赫尔德瓦尔举行；太阳和木星在天蝎宫时在乌贾恩举行；太阳在摩羯宫而木星在金牛宫时就在安拉阿巴德举行。

大壶节相传是源于印度教的神明和群魔为争夺一个装有长生不老药的壶而大打出手，结果把壶打翻，四滴长生不老药落到举办节日的四座城市。印度教徒相信，在这四座城市，特别是在恒河、亚穆纳河与传说中的萨拉斯瓦蒂河三条圣河汇合处（安拉阿巴德以东）沐浴，是特别吉祥的。至于节日最早的文献记载出自玄奘大师，他在《大唐西域记》称之为「无遮大会」。

Kumbh Mela or Kumbha Mela (/ˌkʊm ˈmeɪlə/ or /ˌkʊm məˈlɑː/) is a mass Hindu pilgrimage of faith in which Hindus gather to bathe in a sacred river. Traditionally, four fairs are widely recognized as the Kumbh Melas: the Haridwar Kumbh Mela, the Allahabad Kumbh Mela, the Nashik-Trimbakeshwar Simhastha and the Ujjain Simhastha, although priests at other places have also claimed their local fairs to be Kumbh Melas. These four fairs are held periodically at one of the following places by rotation: Haridwar, Allahabad (Prayaga), Nashik district (Nashik and Trimbak) and Ujjain. The main festival site is located on the banks of a river: the Ganges (Ganga) at Haridwar; the confluence (Sangam) of the Ganges and the Yamuna and the now extinct (disappeared/ dried/ lost in time) Sarasvati at Allahabad; the Godavari at Nashik; and the Shipra at Ujjain. Bathing in these rivers is thought to cleanse a person of all sins.
