Tubmanburg, also known as Bomi and formerly Vaitown, is the capital of Bomi County in Liberia. It lies in the Bomi Hills northwest of Monrovia and was an iron ore and diamond mining centre until it was largely destroyed in the First Liberian Civil War. During the Second Liberian Civil War, it was the headquarters of the Liberians United for Reconciliation and Democracy rebel group. Most residents are members of the Vai tribe.
