Theodore Low De Vinne (December 25, 1828 – February 16, 1914) was an American printer and scholarly author on typography.

Considered "the leading commercial printer of his day,"[3] De Vinne began the professionalization of American printing, as well as commissioning still-popular typefaces and writing extensively on the practice of his trade.

[4] De Vinne was born at Stamford, Connecticut, and educated in the common schools of the various towns where his father, an itinerant Methodist minister,[2] had pastorates.

[13] In 1886, with his business greatly expanded and seeking to increase its printing capacity, he moved the company to the De Vinne Press Building on Lafayette Place, a model plant designed by himself in collaboration with the architects Babb, Cook & Willard.

[19] In 1865 De Vinne was a co-founder of the Typothetae, a trade organization of master printers, which was a predecessor of the Printing Industries of America.
