The Shonan Monorail (湘南モノレール, Shōnan Monorēru) is a suspended SAFEGE monorail in the cities of Kamakura and Fujisawa in Kanagawa Prefecture, Japan. It is operated by the Shonan Monorail Co., Ltd. (湘南モノレール株式会社, Shōnan Monorēru Kabushiki-gaisha) which belongs to Michinori Holdings, and opened on March 7, 1970, the first monorail of its kind in Japan.
Trains run on a 6.6 km (4.1 mi) line called the Enoshima Line. It is used by commuters that work in Tokyo or Yokohama, tourists visiting Enoshima, and, in summer months, city dwellers who are visiting the parks or baths of Enoshima.
The monorail was built by Mitsubishi Heavy Industries, and the line opened March 7, 1970 between Ōfuna and Nishi-Kamakura. The rest of the line opened on July 1, 1971.
Until 2018, the monorail company was part owned by Keihin Kyuko Electric Railway because the monorail line runs over "Keihin Kyuko Line" which was a toll road operated by Keikyu. Seibu Railway also had investment in the company because Kokudo which was a subsidiary of Seibu Group developed land around Kataseyama Station.
In May 2015, most shares of this monorail line and company were transferred to Michinori Holdings from Mitsubishi Group.
In 2018, this company became a wholly subsidiary company of Michinori Holdings.
The Shonan Monorail Enoshima Line (江の島線, Enoshima-sen) travels 6.6 km (4.1 mi) every seven to eight minutes between Ōfuna Station and Enoshima, making six stops. The average length of a single trip is 14 minutes. The line includes two tunnels (between Shōnan-Fukasawa and Nishi-Kamakura stations, and between Mejiroyamashita and Shōnan-Enoshima stations). The line's maintenance workshop is located at the Shonan Monorail Headquarters in Kamakura City.

As of July 2016[update], the line is operated using a fleet of seven three-car aluminium-bodied 5000 series trainsets. The 5000 series is equipped with a VVVF control device and regenerative brake which allows for smooth acceleration and deceleration. The VVVF inverter control reduces the need for inspection and maintenance because unlike a DC motor, there is no commutator brush or contact switch.
Services were initially operated using a fleet of six two-car 300 series trainsets built by Mitsubishi Heavy Industries. Two sets were increased to three cars from February 1975 to provide additional capacity. The last of the 300 series sets were withdrawn by July 1992, following the introduction of new 500 series trains. The 500 series trains introduced in 1988 were the first air-conditioned trains on the line. The last 500 series train was withdrawn after its last day in service on 26 June 2016.
In the early hours of March 23, 2016 the 7th train of all the new 5000 series (Pink Line) was deliver edto Shonan Monorail HQ Workshop in Kamakura City from Mitsubishi Heavy Industry Mihara Plant in Hiroshima Prefecture.
