Bay of Bangkok
The Bay of Bangkok (, , ), also known as the Bight of Bangkok, is the northernmost part of the Gulf of Thailand, roughly extending from Hua Hin District to the west and Sattahip District to the east. Three of the major rivers of central Thailand empty into the bay - the Chao Phraya and its distributary Tha Chin, the Mae Klong and the Bang Pakong River. The bay forms the coast of 8 provinces, them being clockwise: Prachuap Khiri Khan, Phetchaburi, Samut Songkhram, Samut Sakhon, Bangkok, Samut Prakan, Chachoengsao, and Chonburi.

There are some islands off the eastern shores of the bay, like Ko Sichang, Ko Lan and Ko Phai.
