TheChikuhō Main Line (筑豊本線,Chikuhō-honsen) is a railway line inFukuoka Prefecture, Japan, operated byKyushu Railway Company (JR Kyushu). It connectsWakamatsu Station inKitakyushu withHaruda Station inChikushino. BetweenOrio Station and Haruda Station, as well as fromKeisen Station via theSasaguri Line toYoshizuka Station, the line functions as an alternate route to theKagoshima Main Line.

As of 2021, the Chikuho Main Line is the third shortest of allJapan Railways Group lines named Main (or trunk) Line (not counting theJR Shikoku main lines, which were stripped of their designation after JR Shikoku started operating). For comparison, the shortest isHidaka Main Line (30.5 km), after the closure of 116.0 km due to storm damage in 2015.

The line is divided into three sections. Each section has an alias.

Wakamatsu Line

Wakamatsu–Orio, 10.8 km

Fukuhoku Yutaka Line

Orio–Keisen, 34.5 km

Haruda Line

Keisen–Haruda, 20.8 km

Some rapid trains pass the stations marked "X".

A pre-series two-carBEC819 series ACbattery electric multiple unit (BEMU) was tested on the line from April 2016,^[1] and entered revenue service on 19 October 2016.^[2] This will be followed by six more trainsets, entering service in spring 2017.^[1]

The 39 km Wakamatsu to Iizuka section was built by the Chikuho Kogyo Railway, opening between 1891 and 1893, with the 12 km extension to Chikuzen Uchino opening in 1895.^{[citation needed]} The company was nationalised in 1907, with the 15 km Chikuzen Uchino to Harada section opening in 1929.^{[citation needed]}

The 25 km section from Wakamatsu to Nogata was double-tracked between 1893 and 1896, with the 4 km Nogata to Kotake section double-tracked between 1904 and 1906. The 8 km Kotake to Iizuka section was double-tracked between 1942 and 1944.^{[citation needed]}
