Yanbu' al Bahr (Arabic: ينبع "spring by the sea"), also known simply as Yanbu, Yambo, or Yenbo, is a major Red Sea port in the Al Madinah province of western Saudi Arabia. It is approximately 350 kilometers north of Jeddah (at ). The population is 188,430 (2004 census). Yanbu's history dates back at least 2500 years, when it was a staging point on the spice and incense route from Yemen to Egypt and the Mediterranean region. Yanbu served as a supply and operational base for Arab and British forces fighting the Ottoman Empire during the First World War. It remained a small port town until 1975, when the Saudi government designated it as one of the country's two new industrial centres (the other being Al Jubayl on the Persian Gulf).
