Quebec Series

The Quebec Series (퀘벡시리즈) is the annual championship series in the Quebecois Baseball Organisation (QBO), the top professional baseball league in Quebec and Shingoryeo, which has been contested since 1968 between the postseason-winning clubs of the QBO's two circuits, the Imperial League and the Royal League. The series is contested in a Best of Seven series, with the winner being awarded the Henri VII Trophy. While commonly associated with autumn, it is often played into early or even mid-November, with the Game 7 being held two weeks prior to the World Baseball Classic on every other year.

Prior to the Quebecois Baseball Organisation's split into two leagues in year 1982, the Quebecois Baseball Organisation used to have an unique playoff system, where the first-place team was given a spot to the Quebec Series following the end of regular season. The other spot of the Quebec Series was then determined by a ladder-styled playoff, where the third and fourth placed team would face each other in a single-game qualifying game. The winner would then face the second-place team in the five-game Playoff Series, with the respective winner qualifying to the Quebec Series.

In the post-1982 changes, both leagues have conducted a league divisional series (ILDS and RLDS) between the second and the third-placed sides, as well as a league championship series between the league pennant race winner and the divisional series winner to determine which teams will advance. Since 2013, the divisional series have once again expanded, this time incorporating all four teams on both leagues to face each other before their respective championship series. Since 2013, the Quebec Series format has also changed from 2-3-2 format to 2-2-1-1-1 format.

The Quebec Series has been contested 84 times following the 2052 Quebec Series, with the IL winning [insert] times and the RL winning [insert] times.
