Borhani (Bengali: বোরহানী) is a traditional yogurt-like drink from Bangladesh. Borhani is made from sour doi, green chili, mustard seeds, black salt, coriander and mint. It is considered by some to be a type of lassi. It is very commonly consumed in Dhaka and Chittagong regions of Bangladesh, where it is served in special events such as weddings and iftar gatherings in Ramadan. It is normally drank after heavy meals such as biryani, morog polao and tehari to aid digestion although appetizer borhanis do exist.

The origin of the name of the drink is unknown. However, the word is most likely to have derived from the Persian term Borani (Persian: بورانی), which denotes a dish made of yogurt and greens.
