Samuel Maciejowski (15 January 1499 – 26 October 1550) was a 16th-century Roman Catholic Bishop of Chełm, Płock and Kraków, in Poland.
[3] As Bishop of Kraków, he was concerned with the level of education of the clergy, was a supporter of a soft approach with dissenters.
In 1546, he ordered an inspection visit of the diocese, which in concept at least, was to limit the influence of the Reformation, but due to the mildness of his character was largely ineffectual.
He gathered around him scholars and poets such that the atmosphere of the cathedral was one of vigorous scientific and literary debate.
He died on 26 October 1550 and was interred in the burial chapel of Our Lady of the Snows in Wawel Cathedral near his nephew, Bernard Maciejowski also a Bishop of Kraków.
