Division General Michał Janiszewski (15 June 1926 – 3 February 2016)[1] was a Polish officer and public official.

A close aide of General Wojciech Jaruzelski,[2] he served for a number of years as his chief of cabinet.

He was a chief of the office from September 1989 until Jaruzelski stepped down on 22 December 1990.

In December 1990 he ended his professional military service and public activity.

He was wrongly declared dead by the Institute of National Remembrance 9 years earlier, which is why he was omitted from the accusation of the group introducing martial law.
