Teheran-ro (Korean: 테헤란로; named for Tehran, Iran) is a street in the Gangnam district of Seoul, South Korea.

The district of Gangnam-gu experienced phenomenal growth and waves of construction, with Teheran-ro becoming one of the busiest streets in South Korea.

The following year, Samneungno street was renamed Teheran-ro, which then ran through a relatively underdeveloped area that had been annexed into Seoul in 1963.

Various South Korean and international financial and business institutions including POSCO, Standard Chartered and Citibank also maintain offices there.

The explosive growth of Teheran-ro is discussed by the architect and researcher Sun-Young Rieh in her Korean-language book Boom or Bust?
