Isaac Winslow (c. 1671 – December 14, 1738) was an American politician and military officer who lived in Marshfield, Massachusetts.
A member of the prominent Winslow family of the Plymouth Colony, he served as a civil and military official in a period marked by political transition.
[citation needed] Winslow was appointed to the Plymouth County Inferior Court of Common Pleas in 1712 and served until 1738, for the last nine years as its chief justice.
As a representative in the legislature's upper house, he and his fellow councilors were to serve as advisors to the Royal Governor in Boston, as well as pass laws and approve government expenditures.
Winslow's term in council was marked by a period of war and turbulent politics; Massachusetts was almost constantly fighting New England natives and French colonists in Canada, and several successive governors would clash with the lower House of Representatives on issues of finance and legislative appointments.
