Gao Jichong (高繼沖) (943–973) was the last ruler of Jingnan during China's Five Dynasties and Ten Kingdoms period. He ruled from 962 to 963 until his country was overrun by Northern Song forces with little resistance.

In the year of 962, Jichong's predecessor Baoxu died. He was then appointed Jiedushi of Jingnan region by the Northern Song court. This was only a ceremonial act since the jiedushi realm of Jingnan remained de facto an independent country.

Later in the year of 962, Zhou Xingfeng, Jiedushi of Wuping died, leaving his son Zhou Baoquan in power. Zhang Wenbiao Prefecture of Heng, a general under Baoquan's command rebelled against Baoquan and consequently drew the attention of the central government. Armed forces were sent to put down Zhang's rebellion. When the Song army was passing through the Jingnan, it easily took control of the capital city of Jingnan, Jiangling. The Song forces did not meet much resistance since Jichong ordered his forces to surrender immediately knowing that it is impossible for him to keep his country any longer under such dire situations.

After the dissolution of the state of Jingnan, he worked as a local officer in Xuzhou. He died in the year 973.

高繼沖（943年 - 973年），字成和（一作贊平），五代十國荊南政權末代君主（荊南節度使）。為高保融之長子，高保勗之姪。

宋太祖趙匡胤建隆三年（962年），高保勗因病去世，遺命高繼沖權判內外軍馬事以繼其位。後來高繼沖亦被宋任命為荊南節度使。

同年，湖南的武平節度使周行逢亦去世，年僅11歲的周保權嗣位，而境內大將張文表叛變，周保權向宋朝求援。建隆四年（963年），宋軍討伐張文表，假道荊南，發生荊湖之戰，趁機控制南平都城江陵（今湖北江陵）城巷，高繼沖只得納地以歸，南平亡。

南平亡後，宋一度仍任命高繼沖為荊南節度使。不久，高繼沖舉族歸朝，被改命為武寧節度使（約在今江蘇、安徽一帶）。

開寶六年（973年）高繼沖於武寧節度使任內去世，贈侍中。高繼沖鎮守彭門（今江蘇徐州），政事委諸僚佐，然有德政，因此被百姓請求留葬當地，但不被宋太祖允許。
