Proton City (Malay: Bandar raya Proton) is a township with industrial, commercial and residential activities spread over 4,000 acres (16 km2) in Muallim District, Perak, Malaysia. It houses the RM1.8 million Proton car assembly plant.
Proton City aimed to be fully developed by 2020. Undertaken by Proton City Development Corp, a joint venture between DRB-HICOM and Proton itself. A core member of Proton Holdings, it started in 1996 with an initial investment of RM250,000, beginning with the construction of the Proton plant. The Proton plant has a workforce of more than 2,000 and most of them are expected to live in the area. When Proton City was fully developed, it would have had a population of about 240,000.
The first settlement in the area - 252 units of apartments - have been handed over to the buyers. These apartments have common facilities that include car and motorcycle parking bays, children's playground, BBQ area, car wash areas, mosque and a nursery/kindergarten on the ground floor of each block and a multipurpose hall. Parcels 19 and 20, completed in 2007 have 1,091 apartments, 336 units of single- and double-storey terrace houses, 86 semi-detached houses, 37 bungalows and 36 shop-offices.
Proton City is also expected to be home to students and staff of the Sultan Idris Education University (UPSI), which a few years ago was known as Sultan Idris Teachers' College. UPSI, occupying 800 acres (3.2 km2) within Proton City, is expected to have a student population of 20,000 within four years.
