Subang Jaya is a residential hub in the Klang Valley in Selangor, Malaysia. It is situated in the district of Petaling. Due to the proximity between them, the much larger area of UEP Subang Jaya (USJ), and also Bandar Sunway are often collectively identifed and referred together with the name Subang Jaya. This is mainly due to the fact that continuous development in the area has physically merged the townships into a conurbation.
