Piotr Franciszek Kołodziejczyk (June 8, 1939, in Poznań[1]–September 2, 2019,[2] in Rekowo Górny)[3] was a Polish vice-admiral, commander of the 3rd Flotilla of Ships and Navy, Minister of National Defence from 1990 to 1991 and from 1993 to 1994, and member of the Sejm of the 10th term.

In 1978 he was sent to study at the Academy of the General Staff of the Armed Forces of the USSR named after Kliment Voroshilov in Moscow.

From July 1990 to December 1991 he was the Minister of National Defence in the governments of Tadeusz Mazowiecki and Jan Krzysztof Bielecki.

After handing over the office to Jan Parys at the end of 1991, he was immediately transferred to the reserve against the will of President Lech Wałęsa, which made it impossible to assume this position.

This situation was the beginning of a conflict between the president and the minister of defense (dismissed in mid-1992), and the General Inspectorate of the Armed Forces was not created.

He was dismissed after a prolonged conflict with President Lech Wałęsa and the Chief of the General Staff of the Polish Army, Tadeusz Wilecki.
