Thomas Cushing, American lawyer and politician, 1st Lieutenant Governor of Massachusetts (died 1788)

Thomas Cushing III was an American lawyer, merchant, and statesman from Boston, Massachusetts. Active in Boston politics, he represented the city in the provincial assembly from 1761 to its dissolution in 1774, serving as the lower house's speaker for most of those years. Because of his role as speaker, his signature was affixed to many documents protesting British policies, leading officials in London to consider him a dangerous radical. He engaged in extended communications with Benjamin Franklin who at times lobbied on behalf of the legislature's interests in London, seeking ways to reduce the rising tensions of the American Revolution.

The lieutenant governor of Massachusetts is the first in the line to discharge the powers and duties of the office of governor following the incapacitation of the governor of Massachusetts. The constitutional honorific title for the office is His, or Her, Honor.
