The Oregon Public Employees Retirement Fund (OPERF) is the retirement and disability fund for public employees in the U.S. state of Oregon established in 1946. Employees of the state, school districts, and local governments are eligible for coverage. A health insurance plan for covered retirees was added to the program in 1987. The program is administered by a twelve-member board of trustees, appointed to three-year terms by the Governor subject to confirmation by the Senate, which also administers the Oregon Savings Growth Plan, a voluntary deferred compensation plan established in 1991.
