Khobar (Arabic: ٱلْخُبَر, romanized: al-Khubar) is a city and governorate in the Eastern Province of the Kingdom of Saudi Arabia, situated on the coast of the Persian Gulf. With a population of 409,549 as of 2022 in the city core and 658,550 in the governorate, Khobar is part of the 'Triplet Cities' area, or Dammam metropolitan area along with Dammam and Dhahran, forming the residential core of the region.

The city was founded alongside Dammam by the Dawasir who moved there in 1923 fearing British persecution with the permission of King Abdulaziz Al Saud. Khobar experienced rapid growth during and after the discovery of oil in Saudi Arabia as it served as the port for the oil exports of Saudi Aramco in the company's early days. Traditionally, Khobar has also been a city of shopkeepers and merchants, and today has several shopping malls in and around it.

The city is the newest in the Dammam metropolitan area, facing the Persian Gulf with its 16-km long Corniche Road, which runs parallel to the city's eastern coast. Khobar is also considered a resort town as its southern suburbs of the city face the Half Moon Bay and host several beaches and beach resorts. By night, the quiet city turns into a bustling one, with some of the largest malls in the kingdom, such as the Mall of Dhahran and the al-Rashid Mall. The city is also home to the historic Suwaiket Street, officially known as Prince Bandar ibn Abdulaziz Street, which is home to some of the oldest markets in the city. The same could said about King Khalid Street and Prince Mohammed Street.

The Khobar governorate is further divided into several municipalities, with Khobar as their capital. 'Issam ibn Abdullatif al-Mulla has been serving as the mayor of the governorate since the Islamic year 1428 AH (2007 CE).

The city shares a similar history with Dammam. In the early 1930s, Khobar was mainly a fishing hamlet inhabited by members of the Dawasir tribe, who moved there in 1923, fearing British persecution with the permission of King Abdulaziz. The tribe settled in Khobar for its proximity to Bahrain as they had hoped to return to their homeland. The Khobar Governorate was incorporated in 1942 and with the discovery of oil in nearby areas, a port was built in the southern parts of the modern city to facilitate the export of petroleum to Bahrain.

The city quickly transformed into a residential hub and a commercial and industrial port. It soon lost these privileges as commercial operations were transferred to the King Abdulaziz Port in Dammam and the petroleum exports were transferred to Ras Tanura. As a result, Khobar retained its status as the residential core of the area, but over time, its streets slowly became densely packed with markets. Its northern waterfront along the Persian Gulf has been transformed into a corniche, with beaches and resorts to the south on Half Moon Bay.

While most of Khobar's districts are built upon the grid system, unlike Dammam, most of the buildings in the city's main districts are a mix of commercial and residential complexes, with masjids of varied designs and colours adorning its many streets.

Islamist militants carried out attacks in 1996 and 2004.
