Kazimierz Romaniuk (born 21 August 1927, Hołowienki, Poland) is a Polish Catholic prelate, and professor of biblical studies.

During the occupation of Poland in World War II, he studied at the clandestine secondary school "Future" in Warsaw, where he graduated in 1944 with a small matura.

At the same time, he gained priestly formation[clarification needed] at the Major Metropolitan Seminary in Warsaw.

His ordination to the priesthood was on 16 December 1951 in the Church of the Purest Heart of Mary in Warsaw by Archbishop Stefan Wyszyński.

[1][2] He further studied from 1956 to 1958 at the Pontifical Biblical Institute in Rome, earning a bachelor's degree in biblical studies, and at the École Biblique in Jerusalem from 1959 to 1961, where after the submission of the work Love of the Father and the Son in the Holy soteriology, he received his doctorate.

From 1971 to 1982, he held the office of the rector of the Higher Metropolitan Seminary and at the same time the Academic Study of Catholic Theology in Warsaw.

He was consecrated by Archbishop Józef Glemp, accompanied by Cardinal Franciszek Macharski and Bishop Władysław Miziołek [pl].

On 25 March 1992, as a result of the reorganization of the administrative divisions in the Church of Poland, Pope John Paul II moved Romaniuk's offices of diocesan bishop to the newly created Diocese of Warsaw-Praga.

In 1999, he visited the diocese of Pope John Paul II during his apostolic nuncio to Poland.

[10] On 26 August, John Paul II accepted his resignation from his duties as the diocesan Bishop of Warsaw-Prague.
