Kilifi is a town on the coast of Kenya, 56 kilometres (35 mi) northeast of Mombasa by road. The town lies on the Kilifi Creek and sits on the estuary of the Goshi River. Kilifi is the capital of Kilifi County and had a population of 122,899 during the 2009 census.

Kilifi is known for its sandy beaches and for the ruins of Mnarani, including mosques and tombs, dating from the 14th to the 17th century.^{[citation needed]}

Kilifi town sits on both sides of the estuary and is linked by the Kilifi Bridge which overlooks the estuary. The south side has the Mnarani ruins and Shauri Moyo beach while the north side is the main part of Kilifi Town and Bofa Beach.

The weather is generally warm throughout the year (above 25 °C) with two seasons of moderate rainfall (about 800–1000 mm). Long periods of rain start around March and last into July, while the short periods start around October and last until December.

The terrain is generally flat with sandy-loamy soils with the common trees being Cocos nucifera, Anacadium occidentale, Azadirachta indica, and Mangifera indica.

Kilifi is a cosmopolitan town with mixed ethnic groups. The predominant inhabitants (about 80%) are from the Mijikenda groups (mainly Giriama and Chonyi). Other groups include the Swahili-Arab descendants, Barawas, Bajunis, Somalis as well as other groups from inland. There is a handful of Indians, and Europeans, mainly British, German and Italian.

Like every coastal town, fishing in Kilifi is one of the historical economic activities. With time, the town has slowly been transforming from a fishing village to basic industrial and service.

The growth of the town was mainly fuelled by the cashew nut milling factory between 1976 and 1990; the district has been a producer of cashews since 1930. The town almost became a ghost town when the factory was closed in 1990 due to a decline in nuts supply, mismanagement of the factory and increased global competition. Other industrial activities include sisal farming at Kilifi Plantations.
