Thomas Mason (1781–1837) was an optician, and mathematical and philosophical instrument maker of Dublin, Ireland. He was a son of Seacombe Mason (1745–1804, a founder of a dynasty of opticians, and scientific and optical instrument makers), and worked in partnership with his brother, Jonathan Mason, trading as T. & J. Mason from 1805 until 1808, and again from 1813 until 1817. While not working in this partnership, he traded under his own name. He served as Optician to His Excellency the Lord Lieutenant in 1837. He was succeeded in business by his son, Seacombe Mason (1808–1892).
