Port-au-Prince Cathedral (Cathédrale Notre-Dame de Port-au-Prince or Cathédrale de Port-au-Prince) is a Roman Catholic cathedral in Port-au-Prince, Haiti. It is visited mostly by tourists because of its remarkable architecture.  

Built between 1884 and 1914, it was dedicated on December 13, 1928, and became the cathedral church of the Roman Catholic Archdiocese of Port-au-Prince. The cathedral was destroyed in the 12 January 2010 earthquake. In March 2012, the Archdiocese of Port-au-Prince launched an international design competition inviting the architects of the world to submit ideas that will inform the reconstruction of the cathedral. A website www.ndapap.org was activated to promote and manage the competition.
