Woody Duh Tyzz-jiun (Chinese: 杜紫軍; pinyin: Dù Zǐjūn; Pe̍h-ōe-jī: Tō͘ Chú-kun; born 23 October 1959) is a Taiwanese politician, who was the Vice Premier of the Republic of China from 1 February 2016 to 20 May 2016.

He was the Minister of Economic Affairs (MOEA) of the Republic of China from 10 August 2014 after his predecessor Chang Chia-juch's resignation amid the 2014 Kaohsiung gas explosions.

[7] Duh was born in Beijing and graduated with his bachelor's, master's, and doctoral degrees in forestry at National Taiwan University.

[10][11] Responding to the scandal regarding the adulteration and mislabeling of cooking oil made by Chang Chi Foodstuff Factory Co. in October 2013, Duh said that although the cooking oil company had obtained the Good Manufacturing Practice (GMD) certificate, the company might give wrong information regarding their manufacturing process to the Industrial Development Bureau.

He said that currently the bureau is reviewing the GMD system and might require manufacturers to present its export and import activities and declaration and to allow on-the-spot inspection of their production lines when seeking certification.
