The Johor Bahru Conurbation, also known as the Southern Conurbation (Malay: Konurbasi Selatan; Jawi: كونورباسي سلاتن) in the National Physical Plan,[1][2] is the built-up urban or metropolitan area within and around Johor Bahru in the Malaysian state of Johor, and roughly corresponds to the Iskandar Malaysia corridor.

Introduced in the 4th edition of Malaysia's National Physical Plan, the conurbation encompasses Johor Bahru, Senai, Skudai, Kulai, Pasir Gudang, Tanjung Pelepas, Pontian, Kota Tinggi, Desaru, Pengerang and Bandar Tenggara.

[3][4] The population table is based on the official census of 2020 for the local government areas within the Johor Bahru Conurbation.

[5] The conurbation is served by three railway stations of the KTMB, which are Johor Bahru Sentral, Kempas Baru and Kulai.

It is also linked to Woodlands, Singapore via the Shuttle Tebrau service, and it will be supplanted by the newer Johor Bahru-Singapore RTS.
