TheTreasurer of Illinois is a constitutional officer in theexecutive branch ofgovernment of theU.S. state ofIllinois. Seventy-four individuals have occupied the office of Treasurer since statehood. The incumbent isMike Frerichs, aDemocrat. A formerChampaign County auditor andstate senator, Frerichs was first elected to lead the state treasury in 2014 following a close race withRepublican candidateTom Cross.

The Treasurer is elected for a renewable four-year term during the quadrennial mid-term election. TheIllinois Constitution provides that the Treasurer must, at the time of their election, be a United States citizen, at least 25 years old, and a resident of the state for at least three years preceding the election.^[2]

The Treasurer is charged by Article V, Section 18 of theIllinois Constitution with thesafekeeping andinvestment of the monies and securities deposited into the state treasury.^[3] As such, the Treasurer is not thechief financial officer of Illinois. That role is occupied by a separate elected official, theComptroller. Rather, the Treasurer functions as the chiefbanking andinvestment officer for the state of Illinois. In this capacity, the Treasurerreceives payments made to the state,deposits monies with approveddepository institutions,accounts for andmanages the state'sdaily fund balances, directs and administers theinvestment of the state'sportfolio of operating and proprietary funds,arbitrages bondsissued by theGovernor,services principal and interest payable on state debt, anddisburses public monies in redemption ofwarrants drawn by the Comptroller.^{[4][5][6][7][8]}

Other programs have been assigned to the Treasurer's office by law. For example, the Treasurer collectsestate taxes due the state, approves the encumbrance offederal funds, offers variousimpact investment programs tofarmers,small businesses andundercapitalized communities, and administers bothescheats andunclaimed property accruing to the state.^{[9][10][11][12]} The Treasurer also facilitates tax-advantagedABLE,college savings, andretirement savings programs to Illinoisans and provides a voluntarylocal government investment pool to Illinois' 9,600 or so counties, cities, villages, towns, school districts, and other localities.^{[13][14][15][16]} In addition to these routine functions, the Treasurer is concurrently an ex officio member of the State Board of Investment (ISBI), an independent state agency that oversees the investment of Illinois'public pension funds.^[17] ISBI'sassets under management totaled $31.5 billion at the close of the 2024 fiscal year.^[18]

Aside from functional responsibilities, the Treasurer is constitutionally fifth (behind theLieutenant Governor,Attorney General,Secretary of State, and Comptroller, respectively) in theline of succession to the office ofGovernor of Illinois.^[19][20]

Some observers have perceived an overlap between the offices of Treasurer of Illinois and Comptroller of Illinois, and have therefore proposed constitutional amendments to merge the two offices and earn administrative savings. For example, HJRCA 14, considered by theIllinois General Assembly in 2007-2008, would have merged the two offices into the office of a single State Fiscal Officer.^[24]

In 2011, the incumbent Treasurer along with the Comptroller (also former Treasurer) Judy Baar Topinka introduced legislation to allow voters to decide whether the offices should be merged.^[25] The legislation was opposed byMichael Madigan,Speaker of theIllinois House of Representatives.^[26]
