Chungcheong Province (Korean: 충청도; Hanja: 忠淸道; Korean pronunciation: [tɕʰuŋ.tɕʰʌ̹ŋ.do̞]) was one of the eight provinces of Korea during the Joseon Dynasty.

In 1895, the province was replaced by the Districts of Chungju (Chungju-bu; 충주부; 忠州府) in the east, Gongju (Gongju-bu; 공주부; 公州府) in the centre, and Hongju (Hongju-bu; 홍주부; 洪州府; modern-day Hongseong County) in the west.

In 1896, Chungju and eastern Gongju Districts were reorganized into North Chungcheong Province, and Hongju and western Gongju Districts were reorganized into South Chungcheong Province.

Historic Chungcheong was bordered on the north by Gyeonggi Province, on the north east by Gangwon, the east by Gyeongsang Provinces, on the south by North Jeolla Province, and on the west by the Yellow Sea.

Apart from Cheongju, Chungju, and Gongju, other large or notable cities in the modern-day Chungcheong region include Daejeon, Cheonan and Janghang.
