Kozhikode District is a district of Kerala state, situated on the southwest coast of India. The city of Kozhikode, formerly known as Calicut, is the district headquarters. The district is 38.25% urbanised.

Kozhikode district is bordered by the districts of Kannur to the north, Wayanad to the east, and Malappuram to the south. The Arabian Sea lies to the west. It is situated between latitudes 11° 08’N and 11° 50’N and longitudes 75° 30’E and 76° 8’E.

The history of the district is inevitably intertwined with the history of the city of Kozhikode. Calicut is the anglicized form of Kalikooth, the name used by Arabs to refer to Kozhikode. It was also called the Cock Fort, a usage that may have come from kozhi (Rooster) kodu (fortified). According to the historian K.V. Krishnan Iyer, the word Kozhikode is derived from koyil (palace) kodu (fortified), meaning ‘Fortified Palace’.

The ports of the Malabar Coast have participated in the Indian Ocean trade of spices, silk, and other goods for over two millennia. Kozhikode emerged as the centre of an independent kingdom in the 14th century, whose ruler was known as the Zamorin.
