William Henry (22 April 1783 – 8 March 1839) was a Scottish-born Congregationalist pastor who ministered in Stirling and Leith in Scotland, and at Tooting in England.

These studies were made possible by theologian Robert Haldane, who set up and financially supported religious training seminars in Glasgow, Edinburgh and Dundee.

Partway through his studies, William removed to Glasgow and completed his course there, while occasionally acting as an assistant to a Reverend Mr Ewing.

There, he also engaged in open-air preaching, and had a particular interest in promoting the spiritual welfare of sailors: he was instrumental in obtaining a floating chapel for their use.

[5] He also became the Corresponding Secretary of the Home Missionary Society for many years,[6] and became widely known to the religious public through his office at that institution.
