The treasurer and receiver-general of Massachusetts is an elected constitutional officer in the executive branch of the U.S. state of Massachusetts. Originally appointed under authority of the English Crown pursuant to the Charter of the Massachusetts Bay Company, the office of treasurer and receiver-general (commonly called the "state treasurer") became an elective one in 1780.^{[lower-alpha 1]} Sixty-one individuals have occupied the office of state treasurer over the ensuing centuries. The incumbent is Deb Goldberg, a Democrat who took office January 21, 2015.

The state treasurer is in effect the chief financial officer for the Commonwealth of Massachusetts.^[8] As such, the state treasurer manages the Commonwealth's cash flows and invests the working capital of state agencies and local governments.^[9] The state treasurer is also responsible for issueing, registering, and servicing the Commonwealth's public debt along with administering escheats and unclaimed property that accrue to the Commonwealth.^[10][11] These are core functions shared with other state treasurers.^[12]

Other programs have been assigned to the state treasurer by law. For example, the state treasurer regulates the sale of alcoholic beverages within intrastate commerce, provides tax-advantaged ABLE and college savings programs to Bay Stater residents, and manages the state lottery.^[13][14][15] Likewise, the state treasurer administers deferred compensation plans to public and nonprofit employees along with bonuses to veterans, servicemembers, and military families domiciled in Massachusetts.^[16][17]

Aside from these functional responsibilities, the state treasurer is ex officio chair of the Massachusetts Clean Water Trust, the Massachusetts School Building Authority, the Massachusetts State Retirement Board, and the Pension Reserves Investment Management Board.^{[18][19][20][21]} These independent agencies are governed by multimember boards attached to the Office of the Treasurer and Receiver-General for administrative purposes.
