The Jōban Line (常磐線 Jōban-sen?) is a railway line in Japan operated by East Japan Railway Company (JR East). It begins at Nippori Station in Taitō, Tokyo and follows the Pacific coasts of Chiba, Ibaraki, and Fukushima Prefectures before the line officially ends at Iwanuma Station in Iwanuma, Miyagi. However, most trains originate at Ueno rather than Nippori; likewise, many trains continue past Iwanuma onto the Tōhoku Main Line tracks to Sendai.
As of August 2014[update], two segments of the Joban Line are closed in the wake of the 2011 Tōhoku earthquake and tsunami and Fukushima Daiichi nuclear disaster. The segment between Hirono and Haranomachi, which runs through the exclusion zone surrounding the Fukushima Daiichi nuclear meltdown, is closed indefinitely, while the segment between Hamayoshida and Sōma is under reconstruction and served by an interim bus service. JR East is currently inspecting the segments between Hirono and Tomioka and between Namie and Haranomachi in preparation for the surrounding areas being cleared for re-settlement, and plans to reconstruct the track and stations between Hamayoshida and Komagamine in new positions located farther inland, targeting completion by 2017.

The Jōban Line connects Tokyo and the Tōhoku region. After the opening of the Tōhoku Shinkansen in 1982, the Jōban Line was split into two parts at Iwaki: south of Iwaki is double track, and north of Iwaki is single track.
From 2007, until the Fukushima disaster in 2011, the Jōban Line was typically split into four parts for operational purposes.
- Ueno – Toride: local and rapid services
- Toride – Iwaki: suburban and intercity service beyond Toride
- Iwaki – Haranomachi: few trains travelling beyond Iwaki from either direction
- Haranomachi – Sendai: Greater Sendai area.
- Selected Super Hitachi limited express services which operated between Ueno and Sendai/Haranomachi.
- Before 2007, there were local trains which connected Iwaki and Ueno/Sendai directly.
- For information on limited express services (e.g. Super Hitachi, Fresh Hitachi), please see their respective pages.
- Trains stop at stations marked "●" and pass those marked "｜".
- Stations marked "∥" are double-tracked; those marked "◇" are single-tracked and allow trains to pass.
- Fukushima Daiichi nuclear disaster sections closed since the March 2011

The Mito Railway Co. opened the line in sections between 1889 and 1905. The dates of the individual section openings are given below. After the line was nationalised in 1906, a program of double-tracking commenced in 1910, with the 219 km section between Nippori and Yotsukura completed in 1925. The Hirono - Kido and Ono - Futaba sections were double-tracked in 1976.
The first section electrified was Nippori - Matsudo (at 1,500 V DC) in 1936, and extended to Toride in 1949. The Toride - Kusano section was electrified at 20 kV AC between 1961 and 1963, and extended to Iwanumi in 1967.
The 2011 Tohoku earthquake and tsunami caused severe disruption to the line, with services to Iwaki disrupted for a month, services to Yotsukura disrupted for two months, and services to Hirono disrupted for six months. Services on the isolated Haranomachi - Soma section were restored 9 months after the disaster, and services from Iwanuma to Hamayoshida took two years to be restored. Services on the Hirono - Tatsuta section returned on 1 June 2014. The Hamayoshida - Soma section is being rebuilt at a higher, tsumani-proof level, and is scheduled to be reopened in March 2017. It is not known when the Haranomachi - Tatsuta section will be reopened, as it is largely within the exclusion zone declared following the meltdown of the Fukushima Dai-ichi nuclear power-station, with the Ono - Futaba section of the line within approximately 2 km of the epicentre of the meltdown.
