North Jeolla Province, officially Jeonbuk State (Korean: 전북특별자치도; lit. Jeonbuk (North Jeolla) Special Self-Governing Province), is a Special Self-governing Province of South Korea in the Honam region in the southwest of the Korean Peninsula. Jeonbuk borders the provinces of South Chungcheong to the north, North Gyeongsang and South Gyeongsang to the east and South Jeolla to the south.

Jeonbuk State emerged in 1896 from the northern part of the old Jeolla province, one of the Eight Provinces of Korea. Originally North Jeolla Province, it was renamed Jeonbuk (a shortening of North Jeolla) on January 18, 2024 concurrent with the territory gaining more autonomy and being classified as self-governing rather than as a regular province. The special bill on the creation of the special autonomous province of North Jeolla is a project put forward by the People Power Party in August 2022 in accordance with Article 6 of the special law on the establishment of special autonomous provinces. It is the 3rd province after the provinces of Jeju and Gangwon to obtain this status.

Jeonju is the capital and largest city of Jeonbuk, with other major cities including Iksan, Gunsan and Jeongeup.

Jeolla Province, including North Jeolla, was the first province/state out of the Eight Provinces system to have its 1000th year anniversary in 2018, as the name 'Jeolla-do' was established in 1018, during Hyeonjong of Goryeo's 9th year in power.
