Udupi cuisine (Tulu: ಉಡುಪಿ ವನಸ್, Kannada: ಉಡುಪಿ ಊಟ) is a world-renowned cuisine of South India. It forms an important part of the Cuisine of Karnataka and takes its name from Udupi, a town on the southwest coast of India in the state of Karnataka. The Udupi cuisine has its origin in the Ashta mathas of Udupi founded by Madhvacharya.

Udupi cuisine comprises dishes made primarily from grains, beans, vegetables, and fruits. The variety and range of dishes is wide, and a hallmark of the cuisine involves the use of locally available ingredients.

It adheres strictly to the Satvik tradition of Indian vegetarian cuisine, using no onions or garlic, as well as no meat, fish, or shellfish. However, the cuisine may also be adapted for those who consume these restricted items.In order to follow tradition of chaaturmasa vrata, which is restriction of certain food ingredients in certain period or season may have led to innovation of variety of dishes in Udipi cuisine.Pumpkins and gourds are the main ingredients in sambar, a stew prepared with ground coconut and coconut oil as its base.

Udupi (Tulu:ಉಡುಪಿ, Konkani:उडुपी and Kannada:ಉಡುಪಿ) is a town in the south-west Indian State of Karnataka. It is the headquarters of Udupi District. Udupi is notable for the Krishna Temple, and lends its name to the popular Udupi cuisine. Udupi, also known as Rajata Peetha and Shivalli (Shivabelli), a centre of pilgrimage, is situated about 58 km north of Mangalore and about 422 km north-west of Bangalore.

It is widely believed that the name of Udupi was derived from its Tulu name Odipu. The Tulu name in turn is associated with a temple at Malpe, devoted to Vadabhandeshwara. Another story is that the name Udupi came from the combination of the Sanskrit words Udu and Pa, which mean "stars" and "lord." According to legend, the moon's light was once reduced due to a curse by King Daksha, whose 27 daughters (the 27 stars, according to Hindu astrology) were married to the moon. The moon prayed to Lord Shiva to get back its original shine. Lord Shiva was pleased with the moon's prayer and restored its shine. Legend says that the moon and his wives made their prayer at the Chandramouleeshwara temple at Udupi, creating a linga that can be seen even today. According to this story, therefore, Udupi means the land of the "lord of the stars," the moon.
