Bangsar is an affluent residential suburb on the outskirts of Kuala Lumpur, lying about 4 kilometres (2.5 mi) south-west of the city centre. It is part of the Lembah Pantai parliamentary constituency. Bangsar is administered by Dewan Bandaraya Kuala Lumpur (DBKL) unlike other townships in the Klang Valley such as Petaling Jaya and Subang Jaya which have their own municipal councils. Neighbourhood residents' associations and business councils play a part in communicating with the local authority but they exercise no legal or administrative power.
