Monroe Correctional Complex is a Washington State Department of Corrections men's prison located in Monroe, Washington, United States. With an operating capacity of 2,500, it is the second largest prison in the state. It opened in 1910, 21 years after statehood.
Vocational classes offered at MCC include printing, information technology and personal computer support specialist, and inmates can earn a GED while incarcerated. An independent non-profit, University Beyond Bars (UBB), offers college courses as a volunteer organization, and some people incarcerated at MCC have earned associate degrees despite the prohibition of state funding for post-secondary education.
A staff-supervised youth program is offered to high school and middle school students. It is designed to deter students from becoming involved in a criminal lifestyle by meeting selected inmates who tell them about the choices they made which led to their incarceration.
Class II and III jobs are located within MCC. Class III jobs provide essential services to the facility such as maintenance, janitorial, clerical warehouse workers, and kitchen work. Class II jobs are designed to reduce the cost of goods and services to state agencies and other tax-supported entities. These include laundry services, a print shop, a license tab shop, and the panel program. Class I industries were once housed at MCC, but were eliminated in July 2004 as a result of a Washington Supreme Court decision that held that inmates cannot be employed by private commercial enterprises.
Inmates have access to classification and mental health counselors at MCC, in addition to a wide range of paid and volunteer staff.

On January 29, 2011, Officer Jayme Biendl was strangled to death with an amplifying cord by an inmate within prison walls. Inmate Byron Scherf was accused of the murder. Officer Biendl had repeatedly filed work orders for additional security measures to her supervisors which went unanswered. One of her supervisors, Sergeant Jimmy Fletcher, signed a sworn affidavit that he had signed one of the work orders and forwarded it up the chain of command. In reaction to his knowledge of work orders being submitted. The department began to retaliate against Sergeant Fletcher and several other staff for speaking out. Several complaints were filed against the leadership of Monroe for the retaliatory behavior. In 2013 the Public Employees Relations Commission found in favor of Sergeant Fletcher that the DOC retaliated and held him back from promotional opportunities. In 2018 while assigned as a Lieutenant he obtained information that substantiated that the department management were spreading false information stating his involvement in the aftermath of the murder of Officer Biendl. He attempted to resolve the matter without success, demoted himself back to the rank of Sgt. Shortly afterwards a lawsuit was filed and a settlement was reached out of court in favor of Sgt. Fletcher. He elected to resign after 20 years with the department because of declining health issues due to the retaliatory behavior of the department leadership. In reaction to the murder, Washington DOC Officers now carry pepper spray and a "panic button" in case of emergency. No other changes have been made for Offender activities. Inmate Byron Scherf was found guilty of the murder of Officer Biendl and sentenced to death. However when Governor Jay Inslee was elected into office he placed a moratorium in favor of on all inmates on death row.
During the 2020 coronavirus pandemic, the Monroe complex had eleven positive cases—five staff and six inmates in the same minimum security unit. Over 100 prisoners at the complex rioted on April 8 in response to the outbreak, but were broken up by corrections officers using crowd control tactics and an evacuation of housing units. The following day, Governor Inslee announced plans to release nonviolent offenders and at-risk inmates to lower the risk of infection.
