Thomas Smith Webb (October 30, 1771 – July 6, 1819) was the author of Freemason’s Monitor or Illustrations of Masonry, a book which had a significant impact on the development of Masonic Ritual in America, and especially that of the York Rite.

[1] Webb has been called the "Founding Father of the York or American Rite" for his efforts to promote those Masonic bodies.

At the age of sixteen he was apprenticed to a printer in Boston, and he afterward moved to Keene, New Hampshire, where he worked for some time at his trade.

Smith Webb established a paper staining factory and on 14 September 1797, as appears from the copyright, he published The Freemason's Monitor, or Illustrations of Masonry.

The original draft of the constitution, with all the changes, additions, and interlineations in his own handwriting, is in the archives of St. John's Commandery, Providence, Rhode Island.
