Itaewon refers to an area surrounding Itaewon-dong, Yongsan-gu, Seoul, South Korea. About 22,000 people reside in the district and it is a popular area for residents of Seoul, tourists, expats and U.S. military personnel.

Itaewon is known for serving cuisine that are not widely available in Korea, such as those from India, Pakistan, Turkey, Southeast Asia, Britain, Germany, Italy, France, Portugal, Spain and Mexico. Essentially, it's known as "Western Town," reminiscent of many Chinatowns in Western nations.

Itaewon, along with neighborhoods and attractions like Hongdae, Insadong and Seoul Tower, is one of the most popular places in Seoul for tourists.

Itaewon was long known as a hub for high quality counterfeit goods, but those products have largely disappeared. Some authentic goods that are only produced in Korea for the international market, as well as some authentic imports are also available. Itaewon is known for its clothes makers who produce custom-made shirts and suits.

Aside from the local businesses, there is a rich community of international business owners, including a pie shop owner from the U.S.A. (Tartine), authentic American and Canadian burgers, a wine bar, an Austrian delicatessen (with an array of cheeses and meats), a veterinarian/pet groomer with an excellent reputation, a chiropractor from Oregon, doctors and nurses, pharmacists and grocery shop owners.
