William Thompson Bacon (August 24, 1812 – May 18, 1881) was an American minister, editor, and author.
He entered Yale College at the age of 21, after having spent several years in mercantile life, and graduated in 1837.
After graduation, he studied theology in the Yale Divinity School for three years, and was ordained the pastor of the Congregational Church in Trumbull, Connecticut on December 28, 1842, which he resigned from on account of ill health, May 28, 1844.
A great sufferer, for the most of his life from dyspepsia and erysipelas, he died after a week's illness, in Derby, May 18, 1881, aged nearly 69 years.
He was, if not the earliest to suggest, one of the most earnest supporters of the Yale Literary Magazine, of which he was one of the first board of editors.
