Ding Jianxiu (simplified Chinese: 丁鉴修; traditional Chinese: 丁鑑修; pinyin: Dīng Jiànxiū; Wade–Giles: Ting Chien-hsiu, Hepburn: Tei Kanshū, 1886–1944) was a politician in the early Republic of China who subsequently served in a number of Cabinet-level ministries of the Empire of Manchukuo.

A native of Gaizhou Liaoning (near Yingkou), Ding was a graduate of the School of Economics of Waseda University in Tokyo, Japan.

After the death of Fengtian clique warlord Zhang Zuolin, Ding worked with Yuan Jinkai towards the independence of Manchuria from the Republic of China.

Following the Mukden Incident in 1931, the Japanese Kwantung Army appointed him to the self-government committee for Fengtian Province.

However, in May 1940 he was appointed to serve on the Privy Council, and helped organize the celebrations marking the 10th anniversary of the foundation of Manchukuo in 1941.
