Colonel George Taylor Denison II (July 17, 1816 – May 30, 1873) was a Canadian lawyer and military officer.

His grandfather, and father George Taylor Denison, acquired substantial wealth in real estate.

[1][5] His father distinguished himself during the War of 1812 and, in 1822, founded the York Dragoons, a cavalry militia unit, which he paid for out of his own funds.

[1] George Taylor Denison II would later command this unit, following his father's example, and paying its expenses out of his own funds.

[1] Denison and several other aldermen resigned to protest what they regarded as corruption on the part of the mayor at that time, John G. Bowes.
