The International Brazilian Jiu-Jitsu Federation (IBJJF) is a for-profit company that hosts several of the biggest Brazilian jiu-jitsu tournaments in the world, including the World Jiu-Jitsu Championship, World No-Gi Championship, Pan Jiu-Jitsu Championship, and European Open Jiu-Jitsu Championship. The company was created by Carlos Gracie, Jr., who is the head of one of the largest Brazilian jiu-jitsu schools, Gracie Barra. The IBJJF uses the ruleset of the Confederação Brasileira de Jiu-Jitsu, which is their sister organization in Brazil. On October 11, 2020, the IBJJF announced that they will begin to allow both heel hooks and knee-reaping for all brown and black belts competing in no-gi tournaments, starting on an undisclosed date in 2021.

IBJJF Gi tournaments

Athletes competing in official IBJJF tournaments can gain ranking points which count towards their position in the official IBJJF rankings. In the 2017–2018 points system first place in weight divisions is worth 9 points, second 3 points, and third 1 point. First place in the open class is worth 13.5 points, second 4.5 points, and third 1.5 points. The IBJJF weight tournaments in terms of their importance in the calendar. The weighting of a tournament is a factor in the calculation of the number of points the athlete can win via their participation. The IBJJF also uses a third criterion for determining ranking points, which is the calendar season the tournament took place. For the 2017/2018 season, ranking points gained at an IBJJF event from 2015/16 were multiplied by 1, 2016/2017 by 2, and 2017/2018 by 3. Points are calculated as follows: Number of points x tournament ranking × year weighting Examples: 2017/2018 World Championship 1st place open division 13.5 for first x 7 tournament ranking x 3 season weighting = 283.5 points 2015/2016 British National 2nd place medium heavy division 3 for second x 1 tournament ranking x 1 season weighting = 3 points The Gi tournaments in the 2017/2018 season along with their tournament weighting are listed below.

IBJJF No-Gi Tournaments

As of December 2017, the IBJJF does not have a separate athlete ranking for No-Gi tournaments although states on its ranking page that "No-GI ranking and system coming soon". The No-Gi events in the 2017/2018 calendar are listed below.

IBJJF special events

Alongside their open tournaments, the IBJJF has also staged a number of special events over the years as well. This originally began with the introduction of the IBJJF Grand Prix, an invitation-only tournament that took place on a single night and was only contested in either one or two weightclasses at each event. In 2022, the IBJJF announced that they would be opening up IBJJF Grand Prix events to women as well, and arranged their first ever female tournament. On March 20, 2023, the IBJJF announced a new tournament format called 'The Crown' which was scheduled for later that year.
