Sir Henry Watson Parker, KCMG (1 June 1808 – 2 February 1881) was Premier of New South Wales.

Subsequently he toured France, Holland and Belgium, before securing employment in 1837 as private secretary to Sir George Gipps.

In 1843 Parker married Emmeline Emily, third daughter of John Macarthur, which further linked him to the conservative colonial establishment.

In May of that year he was elected Chairman of Committees (Deputy presiding officer of the upper house) at a salary of £250 (raised to £500 in 1853), and continued to be re-elected to this position until the introduction of responsible government in 1856.

He recommended to Governor William Denison that Parker would be the most likely man to conciliate parties, and that he should be asked to form a coalition government.
