William Mason (fl. 1672–1709) was an English writing-master and stenographer.
Working in London, Mason first tried shorthand in 1659. He started with the system then generally attributed to Jeremiah Rich, though by William Cartwright. After a few years Mason looked for a system of his own.
In 1682 Mason was established as a teacher of writing and shorthand in Prince's Court, Lothbury, near the Royal Exchange, and celebrated for his skill in extremely minute handwriting. In 1687 he had moved his academy to the Hand and Pen in Gracechurch Street, and in 1699 he was settled at the Hand and Pen in Scalding Alley, taking pupils there and at home.
Mason published shorthand systems:
