how often is the world baseball championship

The premier “world” baseball championship that most people mean is the World Baseball Classic (WBC) , and it is held every four years.

How often the WBC is held

• The World Baseball Classic was first played in 2006 and then again in 2009 , making early editions about three years apart.

• After 2009, the schedule was adjusted so that the tournament would run every four years , with events in 2013 , 2017 , and 2023 (the 2021 edition was postponed to 2023 due to the pandemic).

• The next WBC is slated for 2027 , continuing that four‑year cycle.

Other “world” baseball events

• The World Series is a completely different championship: it is the annual MLB title series between the American League and National League champions in the U.S. and Canada, not a global national‑team event.

• There was also an older Baseball World Cup for national teams, which was held more frequently (often every two years) but was discontinued after 2011 and has been largely superseded by the WBC.

So, if you’re asking about the top‑level international “world” baseball championship with pro‑level national teams , the answer is every four years , via the World Baseball Classic.
