Chikuzen Province (筑前国, Chikuzen-no kuni) was a province of Japan in the area of northern Kyūshū, corresponding to part of north and western Fukuoka Prefecture.^[1] Chikuzen bordered on Hizen to the east, and Buzen east, and Bungo to the southeast. Its abbreviated form name was Chikushū (筑州) (a name which it shared with Chikugo Province), although it was also called Chikuyo (筑陽). In terms of the Gokishichidō system, Chikuzen was one of the provinces of the Saikaidō circuit. Under the Engishiki classification system, Chikuzen was ranked as one of the "superior countries" (上国) in terms of importance, and one of the "far countries" (遠国) in terms of distance from the capital.

Ancient Tsukushi Province was a major power center in the Yayoi period, with contacts to the Asian mainland and may have been the site for the Kingdom of Yamatai mentioned in official Chinese dynastic Twenty-Four Histories for the 1st- and 2nd-century Eastern Han dynasty, the 3rd-century Records of the Three Kingdoms, and the 6th-century Book of Sui. During the Kofun period, many burial mounds were constructed and the area was ruled by a powerful clan who held the title of "Tsukushi no kuni no miyatsuko". The semi-legendary 14th ruler of Japan, Emperor Chūai is said to have had a palace in Chikuzen at what is now the Kashii-gū shrine. The area was the launching point for Empress Jingu's purported conquest of Korea, and was the settlement area for many toraijin immigrants from China, Silla and Baekje. In 527, the Iwai Rebellion between rival factions supporting Silla against Yamato rule occurred. In 531, the priest Zensho arrived from Northern Wei and established Shugendo. In 663, the Yamato government, which was defeated by the combined Silla and Tang China forces at the Battle of Hakusonko, decided to establish Dazaifu as a regional military and civil administrative center, and after the Taika Reforms and the establishment of the Ritsuryō system in 701, Tsukushi Province was divided into Chikuzen and Chikugo Provinces.

The kokufu of Chikuzen is believed to have been located in what is now part of the city of Dazaifu, although its exact location has not yet been discovered. The ruins of the Chikuzen Kokubun-ji are located in the same area, and are a National Historic Site. The ichinomiya of Chikuzen Province is Sumiyoshi Shrine, located in Hakata-ku, Fukuoka, although the early records of the province indicate that Hakozaki Shrine was the ichinomiya. ^[2]

At the end of the 13th century, Chikuzen was the landing point for a Mongol invasion force. But the main force was destroyed by a typhoon (later called kamikaze).

In April 1336, Kikuchi Taketoshi attacked the Shoni clan stronghold at Dazaifu. At the time, the Shoni were allied with Ashikaga Takauji in his battles against Go-Daigo. The Shoni were defeated, which led to the suicide of several clan members, including their leader Shoni Sadatsune.^[3]

Chikuzen in the Edo period was almost entirely under the control of Fukuoka Domain, ruled by the Kuroda clan to the Meiji restoration.

In the Meiji period, the provinces of Japan were converted into prefectures.^[4] However, the name of the province continued to exist for some purposes. For example, Chikuzen is explicitly recognized in treaties in 1894 (a) between Japan and the United States and (b) between Japan and the United Kingdom.^[5] It also persists in features such as the Chikuhō Main Line (JR Kyushu) and stations Chikuzen Habu and Chikuzen Ueki. The adjacent Haruda Line includes Chikuzen Uchino and Chikuzen Yamae stations, reflecting the region in the time the rail networks were established.

Per the early Meiji period Kyudaka kyuryo Torishirabe-chō (旧高旧領取調帳), an official government assessment of the nation's resources, Chikuzen Province had 862 villages with a total kokudaka of 633,434 koku. Chikuzen Province consisted of:

• 
  Sumiyoshi, the ichinomiya of the province
• 
  Site of the Chikuzen Kokubun-ji
• 
  Site of Dazaifu
• 
  Fukuoka Castle
• 
  Kuroda Nagatomo, final daimyō of Fukuoka Domain
