Jonah David Jang CON (born 13 March 1944) is a former Nigerian military officer and politician who served as the senator representing the Plateau North senatorial district from 2015 to 2019.

He attended a course on Supply Operations Training (Logistics) in Denver, Colorado, United States and was promoted to the rank of captain in 1972, major in 1975 and wing commander in 1978, serving in most of the Nigerian air formations during this period.

[8] Jang was a founding member of the Peoples Democratic Party in the days that preceded the second military to civilian transfer of power in 1999 ushering the Nigerian Fourth Republic.

[9] In the new millennium democratic dispensation for which Jang had so much fought to wrest power from the military, he made an unsuccessful run for the governorship of Plateau State in an election which was marred by alleged forms of irregularities and malpractices on the platform of the All Nigeria Peoples Party.

According to an ally, James Vwi, Jang was already considering and making a series of consultations on running for the Nigerian Senate to represent Plateau North senatorial district shortly before his opportune moment came.

He was able to craft an alliance with a number of political bigwigs while mobilising an incredible amount of funds and put up a fight in the Plateau PDP gubernatorial primary election of 2006 which he won.

As Governor, Jang embarked on a thorough purge of the Plateau State Civil Service ridding it of unwanted corrupt elements mostly in the form of ghost workers.

However, other forces at large were at play and managed to tip the scales in favour of Simon Lalong of the All Progressives Congress (APC) and he was announced the winner of the election.
