Kiamba, officially the Municipality of Kiamba (Cebuano: Lungsod sa Kiamba; Maguindanaon: Inged nu Kiamba, Jawi: ايڠد نو كيامب; Tagalog: Bayan ng Kiamba), is a 1st class municipality in the province of Sarangani, Philippines. According to the 2020 census, it has a population of 65,774 people.

It is bordered on the west by Maitum, on the east by Maasim, on the north by South Cotabato, and on the south by the Celebes Sea.

Notable residents include Manny Pacquiao. It is the hometown of his wife Jinkee Pacquiao.

The area of what is now known as MAKIMA was first inhabited by T'boli tribes people who mostly occupied the highlands. The lowlands and plains were mostly occupied by Maguindanaons especially Sultanate of Maguindanao then Sultanate of Buayan and the Sangil people who mostly are from Balut and Sangili islands, occupied the areas near the sea. The Ilocanos who are originally from Luzon only came to the area around 1920's onwards as they heed the government's homesteading and resettlement plan. Visayans later followed.

The municipality was formed on August 18, 1947, when Executive Order No. 82 was signed by the government by merging the municipal districts of Kraan and Kling.

Maitum on the west became an independent municipality in 1959. In 1971, Maasim, on the east, also became an independent municipality.

Kiamba is politically subdivided into 20 barangays. Each barangay consists of puroks while some have sitios.

The majority of the population speak Cebuano, although early settlers were of Ilocano origin, as a result of assimilation into the majority Cebuano-speaking society due to the huge influx of migrants from Cebu, Bohol, Siquijor, and other Cebuano-speaking parts of Mindanao residing in the area over the years. There are a lot of Moro people (Sangil and Maguindanaon) who settles in the area long before the Christians from Luzon (and later Visayas) came. One of the indigenous peoples living in mountainous areas of Kiamba is known as T'boli.

The economy of Kiamba is largely based on agriculture with vast ricefields surrounding the municipality. Aqua-culture is the second biggest income earner, notably the culture of milkfish and shrimps (locally called "sugpo" or "lukon") for export. Also, coastal communities depend on deep-sea fishing as a primary livelihood.
