悉多（梵文：सीता）是印度史诗罗摩衍那的女主角，大神毗湿奴化身的罗摩的妻子，因此一般人亦认为悉多是吉祥天女的化身。悉多原是弥提罗国国王遮那加的公主，遮那加年迈无子，作祭祀求神赐子，祭典期间在大地中出现了一个女娃，便是悉多，遮那加认为是天神的恩赐，所以立誓要能拉开湿婆的神弓的人才能成为悉多的丈夫，结果只有罗摩成功拉开神弓，悉多就此成为拘萨罗国的太子纪。后来罗摩自愿放逐，悉多跟随，在放逐期间，罗刹女欲勾引罗摩，但罗摩都不为所动，因此罗刹女要求罗刹王罗波那消灭悉多。罗波那被悉多的美色吸引，希望收为妃子，但悉多不肯，罗波那借机引开罗摩后掳走了悉多。在哈奴曼的协助下，罗摩在楞伽岛之战中击败了罗波那，拯救了悉多。悉多虽然获救，却被罗摩质疑她清白之身，于是悉多走入火堆中，向火神发愿以证清白，最终由火神从火堆中带出悉多，以证其清白之身。罗摩登基后，国民又质疑悉多，悉多只好躲到净修林中誔下双胞胎，双胞胎兄弟俱舍及罗婆得到蚁垤仙人的照顾，变得文武全才。在一次机遇中，罗摩相认了两兄弟，悉多再次向天神许愿以证身，最终悉多得到天神的祝福，回到大地内。
