Raita is a common name of a condiment from the Indian subcontinent, made with dahi (yogurt, often referred to as curd) together with raw or cooked vegetables, more seldom fruit, or in the case of boondi raita, with fried droplets of batter made from besan (chickpea flour, generally labelled as gram flour).

The closest approximation in western cuisine is a side dish or dip, or a cooked salad. It is often referred to as a condiment, but unlike traditional western condiments like salt, pepper, mustard and horseradish that made dishes more spicy, a dish of dahi or raita has a cooling effect to contrast with spicy curries and kebabs that are the main fare of some Asian cuisines. In Indian cuisine, some type of flatbread may be eaten together with raita, chutneys and pickles.
The yogurt may be seasoned with coriander, roasted cumin seeds; mint, cayenne pepper, chaat masala and other herbs and spices.
