Sattahip Bay (Thai: อ่าวสัตหีบ) is a bay in the eastern side of the Gulf of Siam or Gulf of Thailand. It is located in Sattahip District, Chonburi Province, Thailand.

Prince Abhakara Kiartivongse (1880 – 1923), son of King Chulalongkorn, inspected Sattahip Bay in 1922 and saw that it was an ideal place to establish a Naval base. Subsequently, he offered Royal land in Sattahip in order to build the present-day naval facilities and the Royal Thai Naval Academy; the latter would later be established closer to Bangkok though and is now located in Samut Prakan.

Nowadays the Bay is part of the Sattahip Naval Base area, the largest base of the Royal Thai Navy. Occasionally Sattahip Bay has been invaded by jellyfish. Much to their chagrin, the Thai Navy is often referred to as the Jellyfish Patrol.

Sattahip Bay lies at the southern end of Chonburi Province. It is open towards the southwest and is bound by limestone rock formations forming peninsulas to the west over Laem Chalak and to the southeast at Khao Chong Khaep.

There are several islands in the bay area, the largest being Ko Tao Mo, located towards the western end of the mouth of the bay. Smaller Ko I Lao is the island located further off the shore.
