The World Sudoku Championship is an annual international sudoku competition organised by a member of the World Puzzle Federation. The first one was held in Lucca in 2006. National teams are determined by local affiliates of the World Puzzle Federation. The competition typically consists of 50 or more puzzles solved by all competitors over multiple timed rounds, including classic sudoku and variations, followed by a playoff for the top qualifiers to determine a champion. Examples of rounds include the Relay round, where an answer from one puzzle contributes digits to the start of the next sudoku, and the "World Record" round, in which solvers competed to set a Guinness World Record for fastest sudoku solution.

Of the 8 championships held so far, Thomas Snyder of USA (2007, 2008 and 2011) and Jan Mrozowski of Poland (2009, 2010 and 2012) have been the most successful winners with three individual titles each, they succedeed to Jana Tylova of Czech Republic (2006) who won the first individual championship.

From 2007 there has also been a team competition. Japan (2007 and 2012) and Germany (2010 and 2011) have both won this title twice; Czech Republic (2008), Slovakia (2009) and China (2013) also won a title each.

Starting from 2011, the event has been held alongside the World Puzzle Championship. The 2014 Championship was held in London, UK.
