Summer Supercard[1] was a multi-promotional professional wrestling supershow produced by Ring of Honor (ROH) also featuring wrestlers from Mexico's Consejo Mundial de Lucha Libre (CMLL), the National Wrestling Alliance (NWA), and Japan's New Japan Pro-Wrestling (NJPW) promotions and took place on August 9, 2019, at the Mattamy Athletic Centre in Toronto, Ontario, Canada.

Therefore, there was a NWA-sanctioned match scheduled to be on the card: Nick Aldis defending his NWA Worlds Heavyweight Championship against a Villain Enterprises member of Marty Scurll's choosing.

[3] Summer Supercard featured professional wrestling matches, involving different wrestlers from pre-existing scripted feuds, plots, and storylines that played out on ROH's television programs.

Stuart Carapola of Pro Wrestling Insider praised the majority of the matches, overall calling the show "terrific".

[4] Justin Knipper of Wrestling Observer Newsletter stated "this was a decent show, but the standout match featured six guys who aren’t even under contract to ROH."
