William Moses (1623?–1688) was an English academic and lawyer, Master of Pembroke College, Cambridge, during the Interregnum and later serjeant-at-law.
Benjamin Laney had been ejected from the mastership in March 1644, and the post had been successively held by the intruded Richard Vines and Sidrach Simpson.
Moses was a good administrator, securing for his college the possession of the benefactions of Sir Robert Hitcham, and rebuilding much of the fabric.
According to Alexander Gordon writing in the Dictionary of National Biography, Moses was a religious puritan, influenced when young by the Institutions of William Bucanus, which he read at Christ's Hospital in the English version by Robert Hill.
A short Latin poem by him is included in Academiae Cantabrigiensis Σώστρα, Cambridge, 1660, a congratulatory collection on the restoration of Charles II.
