Malabar matthi curry, also known as fish curry, is a traditional Kerala dish. It is usually prepared with fish semi-stewed in a Kerala-style sauce that typically includes a blend of spices and assorted vegetables, such as okra or onions. While sardines are commonly used, the dish can be prepared with a variety of fish, such as mackerel, kingfish, or pomfret. It is usually served with rice or tapioca. The dish is most popular in Kerala, Goa, and Sri Lanka, where rice and fish are staple foods. Other variations may include adding tamarind juice or coconut milk.

The origins of the modern dish can be traced back to Tamil Nadu and Kerala.

Fish curries are also eaten in Sri Lanka and other countries. The dish is also mass-produced, processed and packaged in cans and flexible pouches for consumer purchase.
