The Sadleirian Chair is a Professorship in pure mathematics at Cambridge University.
It was established in 1701 by Lady Sadleir . She made provisions in her will for lectures in algebra to be funded at the university. She died in 1706 and the lectures began in 1710. In 1860 the lectureship was changed to a professorship.

Note: Some references, e.g., Encyclopaedia Britannica, 15th edition, refer to the subject as Sadlerian Chair.
