Dhahran (الظهران) is a city located in the Eastern Province, Saudi Arabia. With a total population of 240,742 as of 2021, it is a major administrative center for the Saudi oil industry. Together with the nearby cities of Dammam and Khobar, Dhahran forms part of the Dammam Metropolitan Area, which is commonly known as greater Dammam and has an estimated population of 4,140,000 as of 2012.
Large oil reserves were first identified in the Dhahran area in 1931, and in 1935, American company Standard Oil drilled the first commercially viable oil well. Standard Oil later established a subsidiary in Saudi Arabia called the Arabian American Oil Company (ARAMCO), now owned by the Saudi government and known as Saudi Aramco. Dhahran has been the home of Saudi Aramco's headquarters for 80 years and is its first and largest gated compound with more than 50,000 residents. Employees and dependents of Aramco, known as Aramcons, have a tendency to use Dhahran to solely refer to the Aramco camp while using Khobar and/or Dammam to refer to the area outside the camp.
Dhahran is unusual in that a large portion of it is made up of gated areas including Saudi Aramco's headquarters and residential camp, the King Fahd University of Petroleum and Minerals (built by Aramco) and the King Abdulaziz Air Base. Dhahran is also home to the Mall of Dhahran, one of the biggest shopping complexes in the Eastern Province.
Dhahran is a short distance west of downtown Khobar. It is about south of Dammam. Both are older Saudi port cities on the coast of the Persian Gulf. Looking farther afield, Dhahran is northeast of Abqaiq, and southeast of Qatif and, further north, Ras Tanura, a major oil port. The Kingdom of Bahrain is also within easy driving distance to the east (about 32 km [20 mi]), across the King Fahd Causeway, from Khobar.
There are several notable landmarks in Dhahran City including KFUPM clock tower as well as Saudi Aramco's Al-Midra Tower and King Abdulaziz Center for World Culture.
