Penang is a state in Malaysia and the name of its constituent island, located on the northwest coast of Peninsular Malaysia by the Strait of Malacca. It is bordered by Kedah in the north and east, and Perak in the south. Penang is the second smallest Malaysian state in area after Perlis, and the eighth most populous. It is composed of two parts – Penang Island, where the seat of government is, and Seberang Perai (formerly, and occasionally Province Wellesley) on the Malay Peninsula. Highly urbanised and industrialised Penang is one of the most developed and economically important states in the country, as well as a thriving tourist destination. Penang has the third-highest Human Development Index in Malaysia, after the federal territory of Kuala Lumpur and the state of Selangor. Its heterogeneous population is highly diverse in ethnicity, culture, language, and religion. A resident of Penang is colloquially known as a Penangite.
