Philipp Krementz (1 December 1819 – 6 May 1899) was a German Catholic bishop, created Cardinal in 1893.

[1] Philipp Krementz was born, the son of a butcher, in Koblenz in 1837 and began to study theology in Bonn, which he continued in Munich in 1839.

The chapter of Frombork cathedral elected Krementz, who was favored by the Queen of Prussia and whom he knew personally, as Bishop of Warmia on 22 October 1867.

In 1872, he excommunicated five clergy from his diocese who were against the infallibility of the Pope, which led to a conflict with the Prussian state.

In March 1885, the Vatican and the Prussian State agreed on the replacement of the vacant chair of the Archbishop of Cologne.
