Sattahip (Thai: สัตหีบ, pronounced [sàt.tā.hìːp]) is a district (amphoe) in Chonburi province, Thailand. It is at the southern tip of the province southeast of Bangkok. In 2014, the district had a population of 157,000 in an area of 348.122 km².

Neighboring districts are Bang Lamung to the north, Ban Chang of Rayong province to the east, and the Gulf of Thailand to the south and west.

The history of Sattahip begins with a woman named Jang, who owned much land in Sattahip District. Admiral Prince Abhakara Kiartivongse, a son of King Rama V, was sent to create a naval base at Sattahip. He thought it was perfect owing to the many small islands that protected it from wind and waves. He ask Jang for land on the seacoast, and she donated the area that the prince needed.

In Thai, satta (Thai: สัต) means 'seven', while hip (Thai: หีบ) means 'box' or 'barrier'. Thus Sattahip means the 'seven barriers', which are the islands that protect the coast of the district. These islands are Ko Phra, Ko Yo, Ko Mu, Ko Tao Mo, Ko Nen, Ko San Chalam and Ko Bo.

The minor district (king amphoe) Sattahip was created on 1 April 1937 by separating the sub-districts Sattahip and Na Chom Thien from Bang Lamung district.^[2] It was upgraded to a full district in 1953.^[3]

The district is divided into fivetambons, or sub-districts, which are further subdivided into 41 mubans, or villages.
