Ha Gyeong-bok (1377-1438) was an early Joseon military officer whose ancestral seat is Jinyang (Jinju); his posthumous title was Yangjeong. His father is said to have been Ha Seung-hae and his mother of the Boseong Seon clan, and he is described as a seventh-degree nephew of Ha Ryun. He passed the military examination in 1402.
He served as military commander of Gyeongwon in 1410 and from the intercalary twelfth month of 1422 guarded the north as commander of Hamgil Province. By conciliating and subduing the Jurchen and urging the creation of Jongseong and Gyeongheung counties, he is credited with laying the groundwork for the Six Garrisons; the Sejong Sillok says he pacified the north for fifteen years. He is also said to have taken part in compiling the military manual Gyechuk Jinseol.
He later served as Pan-Jungchuwon-sa (1432), Inspector-General of Hamgil (1433) and Chanseong of the State Council (1435). Dismissed in 1436 over a dispute about reports on an epidemic in Hamgil, he was then named commander in Right Gyeongsang and died in August 1438 in the camp at Hapo.
