The World Aquatics Water Polo World Rankings, formerly the FINA Water Polo World Rankings, are World Aquatics' ranking system for national teams in water polo.

The ranking system, introduced in 2025, compares teams based on the weighted average rating points they earn in games over the last eight years. Teams earn a certain amount of rating points for each game based on the margin of victory/defeat, site of game and strength of opponent. Each game's rating points are then weighted by factors including the time of game, competition/region, competition stage and round reached.

The ranking system produces four separate rankings: Men's, Women's, Boys and Girls. The Boys' and Girls' age group rankings are based on combined results across all age divisions from under-16 to under-20 matches.

History In their previous ranking system, World Aquatics (formerly FINA) awarded teams points based on placements in final tournaments including the Olympic Games, World Championships and continental championships.

Calculation Teams are ranked based on the total points they earn in all matches played over the last eight years as follows:

where: TP – Total points – Rating points for match – Match Weighting for match

Rating Points (RP) Teams earn a certain amount of rating points per match based on the margin of victory/defeat, site of game and strength of their opponent, calculated as follows:

where: – Rating Points – Basis Points – : Home, Away and Neutral Matches Points – Opposition Ranking Points

where: – Match Weight – Time Decay factor – Competition Weight – Round weight
