There isn’t a single official, permanent “pi memory champion,” but there are a few major record‑holders people usually mean when they ask this.

The big pi memorizers

  • Current top-ranked pi reciters (by checked digits) are tracked on the independent Pi World Ranking List, which lists competitors by how many digits they have correctly recited and when.
  • Akira Haraguchi (Japan) is widely known in media and math circles for reciting more than 100,000 digits of pi; in a 2015 feature he was credited with having memorized 111,700 digits, making him a legend among memory enthusiasts, although not all of his feats are listed as official Guinness records.
  • Rajveer Meena (India) set a Guinness World Record in 2015 by correctly reciting 70,000 digits of pi while blindfolded, a feat that took nearly 10 hours.
  • A World Pi Federation exists and organizes long‑term memory competitions around pi and similar challenges, but it treats these as ongoing competitive events rather than granting a single lifetime “champion” title.

Why the answer is messy

Different organizations track different things:

  • Independent rankings (like Pi World Ranking List) focus on number of checked digits and date of performance.
  • Guinness World Records focuses on verified record attempts under strict conditions (time, conditions like blindfold, official witnesses).
  • Media and math communities often talk about people like Haraguchi as the de facto “pi champions” because their totals are so huge, even if not all attempts are in Guinness.

So, if you just want a name to attach to “pi memory champion” today:

  • For Guinness‑style official record : Rajveer Meena (70,000 digits).
  • For legendary highest claimed digits : Akira Haraguchi (over 100,000 digits, reported as 111,700).

In forum or casual talk, people will usually mean one of those two when they ask “who is the pi memory champion?”
