Senai (GPS: 1.60139, 103.64536) is a town 25 km to the northwest of Johor Bahru that is best known as home for the Senai International Airport. It is located to the north of Lima Kedai, to the northwest of Kempas, and to the south of Kulai.
Senai is said to have been named after a local tree called pokok senai. It was a sleepy town until the construction of Senai airport brought about some development to the area. The old town centre is still around. It comprises mostly pre-war shophouses along the Old Trunk Road (Federal Route 1), which is known here as Lebuhraya Senai.
