Rojak (Malaysian and Singaporean spelling) or Rujak (Indonesian spelling) is a traditional fruit and vegetable salad dish commonly found in Indonesia, Malaysia and Singapore. The term "Rojak" is Malay for mixture.

In Malaysia and Singapore, the term "rojak" is also used as a colloquial expression for an eclectic mix, in particular as a word describing the multi-ethnic character of Malaysian and Singaporean society.

In Indonesia, among the Javanese, rujak is an essential part of the traditional prenatal ceremony called Tujuh bulanan (literally: seventh month). Special fruit rujak is made for this occasion, and later served to the mother-to-be and her guests, primarily her female friends). It is widely known that the sweet, spicy and sour tastes of rojak are adored by pregnant women. The recipe of rujak for this ceremony is similar to typical Indonesian fruit rujak, with the exceptions that the fruits are roughly shredded instead of thinly sliced, and that jeruk bali (pomelo/pink grapefruit) is an essential ingredient. It is believed that if the rujak overall tastes sweet, the unborn would be a girl, and if it is spicy, the unborn baby is a boy.
