Ise Electric Railway (伊勢電気鉄道, Ise Denki Tetsudō), usually abbreviated as Iseden (伊勢電), was a private railway company that operated mostly in Mie Prefecture, Japan, for 25 years from 1911 to 1936, when it was absorbed by Sangū Express Electric Railway. At its height, Iseden operated three train lines, two of which it planned and built, that serviced the cities of Yokkaichi, Tsu, Suzuka, Matsusaka, Ujiyamada, and Ōgaki. Much of the infrastructure of Iseden is now owned by Kintetsu and remains in use today.
The name "Ise" was chosen for use in the company's name because the area of Japan that Iseden served, northern and central Mie Prefecture, was called Ise Province during the Edo era before the modern prefecture system was put into effect.
