Samuel Adams Sr. (1689–1748) was an American brewer, and father of Samuel Adams.
He was born in Boston, on May 16, 1689. He was a Deacon in the Congregational Church.
He was a Boston Caucus member with Elisha Cooke. In 1740, he helped create a Land Bank, in Massachusetts Bay Colony, using paper money to promote commerce, with a scarcity of gold and silver coins. In July 1741, the House of Commons passed a bill destroying the land bank, by making shareholders liable for the bank's debts.
In 1713, he married Mary Fifield. They had twelve children. Three survived into adulthood, including Samuel Adams.
