Karel Aeneas Jacobus de Croeser (Charles-Enée-Jacques de Croeser) (14 July 1746 - 22 January 1828) served as the Mayor of Bruges (Brugge) between 1803 and 1813, and then for a second ten-year term from 1817 to 1827. He was the first man elected to the post after the contentious establishment of the United Kingdom of the Netherlands in 1815. By that time, he had already achieved a measure of notability more broadly as a poet and genealogist.
