Iskandar Puteri is a city in Johor Bahru District, Johor, Malaysia. Situated along the Straits of Johor at the southern end of the Malay Peninsula, it is also the southernmost city in Peninsular Malaysia（and thus the southernmost city of continental Eurasia). Iskandar Puteri is adjacent to the city of Johor Bahru, both anchoring Malaysia's third largest urban agglomeration, Iskandar Malaysia, with a population of 1.8 million
Historically the area was an old Malay and Orang Asli fishing village and fort that has existed since Srivijaya and part of the Johor Bahru which was then known as Ujong Medini or Tanjung Puteri. It is located at the mouth of Tebrau Strait and has the narrowest distance between the Johore mainland to the Singapore, thus nicknamed as Sempit Puteri (literally means, Narrow Princess) in the past.
