Jomtien[a] (จอมเทียน, RTGS: Chom Thian, pronounced [tɕɔ̄ːm tʰīan]) or Jomtien Beach (หาดจอมเทียน, RTGS: Hat Chom Thian, pronounced [hàːt tɕɔ̄ːm tʰīan]) is a town on the east coast of the Gulf of Thailand about 165 km south-east of Bangkok in Bang Lamung District, Chonburi Province.

Jomtien Complex is an important real estate development located a block from the beach, and includes a large group of shophouses, restaurants, bars and stores.

A recent trend has been the opening of many upscale restaurants along Thappraya Road, the main thoroughfare connecting Pattaya and Jomtien.

Songthaews (aka "bahtbus") are the most popular mode of public transportation, and run from Jomtien Beach to north Pattaya.

South of Jomtien Beach, the U-Tapao International Airport (UTP) is open to air traffic, it is about 50 min drive, or 40 km by road.
