Thomas Workman (June 17, 1813 – October 9, 1889) was a Quebec businessman and political figure.
He was born in Ballymacash, Ireland in 1813 and came to Montreal, where his brothers had already settled, in 1827.
In 1834, he was hired as a clerk in a hardware company operated by John Frothingham and his brother William; he became a partner in 1843 and sole owner in 1859.
He served as a volunteer to help put down the Lower Canada Rebellion.
He was elected to the House of Commons in 1867, but did not run again until an 1875 by-election in Montreal West after the sitting member was unseated.
