Xi Qia or Xi Xia (Hsi Hsia; Chinese: 熙洽; pinyin: Xīqià; Wade–Giles: Hsi1-hsia4; Hepburn: Ki Kō; 1883–1950) was a general in command of the Jilin Provincial Army of the Republic of China, who defected to the Japanese during the Invasion of Manchuria in 1931, and who subsequently served as a cabinet minister in Manchukuo.

He contributed to making and a supporter of efforts to create a new Manchu-dominated state in Manchuria after the Xinhai Revolution overthrew the Qing dynasty in China.

As a youth, he studied in Japan at the Tokyo Shimbu Gakko, a military preparatory school for Chinese students, followed by the Imperial Japanese Army Academy.

He rose to the rank of lieutenant general and commanding officer of the Provincial Army of Jilin Province under the Fengtian clique.

Because of transportation difficulties in the cold winter weather it took seven days for Japanese columns to struggle north over the frozen countryside in temperatures of 30° below zero.
