Jeolla (Korean: 전라도 Jeolla-do/Chŏlla-to [tɕʌlːado], "Jeolla province", also spelled Cholla) was a province in southwestern Korea, one of the historical Eight Provinces of Korea during the Joseon Dynasty. It consisted of the modern South Korean provinces of North Jeolla, South Jeolla and the Special City of Gwangju as well as Jeju Island. The provincial capital was Jeonju, the current capital of Northern Jeolla. The entire inland region was formerly called Honam "South of the Lake".

Silla reorganized this territory into 9 "ju" (주) and 5 "gyeong" (경), 3 of the ju belonging to the former Baekje. The northern territory of former Baekje, Ung (Ungju; 웅주; 熊州), corresponds to modern day South Chungcheong.
