Nigel Richards (born 1967) is a New Zealand Scrabble player who is widely regarded as the greatest tournament-Scrabble player of all time. Born and raised in New Zealand, Richards became World Champion in 2007, and repeated the feat in 2011, 2013, 2018, and 2019. He also won the third World English-Language Scrabble Players’ Association Championship (WESPAC) in 2019.

Richards is also a five-time U.S. national champion (four times consecutively from 2010 to 2013), an eight-time UK Open champion, an 11-time champion of the Singapore Open Scrabble Championship and a 15-time winner of the King's Cup in Bangkok, the world's biggest Scrabble competition.

In 2015, despite not speaking French, Richards won the French World Scrabble Championships, after reportedly spending nine weeks studying the French dictionary. He won it again in 2018, and multiple duplicate titles from 2016.

In 2024, Richards accomplished a similar feat by winning the Spanish-language World Championships.

Renowned for his eidetic and mathematical abilities, Richards has been described as a reclusive personality and has rarely been interviewed.
