The ROH Anniversary Show is a professional wrestling event, held annually by the Ring of Honor promotion. The event celebrates the anniversary of the promotion's inaugural show The Era of Honor Begins, which was held on February 23, 2002. To coincide with this, the Anniversary Show is normally held in February, though it occasionally falls into March.
Although most years have seen a one-night celebration, the third year saw three events take place over two weekends. The fifth year went further and had five events in ROH's most popular venues, leading up to a sixth and final show in Liverpool, England across three weekends. Since then, the Anniversary Show has been a single night show. Although ROH began airing live internet pay-per-views in 2009, ROH only began airing the Anniversary Show live from the ninth installment in 2011. All previous events were recorded and sold later on DVD.
