Death Before Dishonor XVIII was a professional wrestling pay-per-view produced by Ring of Honor (ROH). It was the eighteenth event in the Death Before Dishonor chronology. It took place on September 12, 2021. The show was originally supposed to emanate from the RP Funding Center in Lakeland, Florida, but due to a surge of COVID-19 in Florida at the time, the location was changed to the 2300 Arena at Philadelphia, Pennsylvania.
