A Grand Prix, frequently abbreviated GP, is a type of DCI-sanctioned Magic: The Gathering tournament. Grand Prix events are open to all players, with no need to qualify for the event, unlike a Pro Tour or Players Tour event. As a result, these tournaments have had the largest turnouts of any Magic tournaments.
Grand Prix events are split into two days, with the top players advancing to Day 2 and a final single elimination top eight playoff taking place at the end of Day 2. Grand Prix tournaments are the main event of a minimum three-day mini-convention. The term "Grand Prix" can refer to either the tournament or to the entire weekend. Starting in 2019, as part of a broader re-branding, the term "MagicFest" was introduced to refer to the overall event, which includes both the Grand Prix main event and a number of Side Events, which last for only a few hours and which have comparatively smaller prize pools.
