The Western Area or Freetown Peninsula (formerly the Colony of Sierra Leone) is one of four principal divisions of Sierra Leone. It comprises the oldest city and national capital Freetown and its surrounding towns and countryside. It covers an area of 557 km² and has a population of 1,447,271. The Western Area is located mostly around the peninsula and is divided into two districts: the Western Area Rural and the Western Area Urban.
The Western Area is the wealthiest region in Sierra Leone, having the largest economy, financial and cultural center, as well as the seat of the country's national government. Unlike the other regions in Sierra Leone, the western area is not a province.
