The Mattel World Scrabble Championship 2018 was a Scrabble tournament organised by Mattel and Mindsports Academy (MSA) to determine the world champion in English Scrabble held from 23 to 28 October 2018.
The event was split into two divisions according to players' World English-Language Scrabble Players' Association (WESPA) ratings; the top division comprised some 75 players. 35 games were played on the first four days, after which the top eight proceeded to a 3-game quarterfinals, with the winners advancing to a 5-game semifinals on the same day; the top two players, Nigel Richards and Jesse Day, played a best-of-five final the day after for the top prize of €10,000. Richards beat Day 3–1, becoming world champion for an unprecedented fourth time.
