Teunis (Ton) Sijbrands (born 15 December 1949, in Amsterdam) is a Dutch international draughts player who became world champion in 1972.

Sijbrands also had a weekly column about draughts in the Dutch national newspaper de Volkskrant and wrote several books about the game.

On 18 December 2004, in the Dutch village of Lutten, Sijbrands improved the world record for blindfold simultaneous draughts.

In this attempt that lasted 24 hours, he won 20 out of 24 games; the other 4 were draws, which equals a score of about 92%.

Sijbrands regained the world record once more on 19–21 December 2014 in Hilversum, Netherlands.
