Cambridge, Massachusetts, in Middlesex County, has about 121,000 residents (2024 Census Bureau estimate). In Massachusetts the public criminal record is the court file, kept by the Clerk of Courts; the statewide criminal history kept by the Department of Criminal Justice Information Services is open to anyone who asks.

Criminal Cases in the Middlesex County Superior Court
A criminal case from Cambridge is filed in the Middlesex County Superior Court or the District Court and Boston Municipal Court, which take misdemeanors, traffic cases, small claims and civil cases up to $50,000, and the court file, kept by the Clerk of Courts, is the record of it that the public may see.

The Massachusetts Criminal History and Your Own Copy
Massachusetts is one of the states that lets anyone look up another person's statewide criminal history: open access iCORI lets anyone request limited conviction information by name, for $25 a search, through the Department of Criminal Justice Information Services. The result is the repository record, what agencies reported to the state, which is wider than one county's court index but can lag it. The search is on the Department of Criminal Justice Information Services site.
To see your own record, the route is a personal CORI request, free once a year online. The state page SearchSystems verified for it is at mass.gov/massachusetts-criminal-offender-record-information-cori.
Arrest Records Kept Locally in Cambridge
The Middlesex Sheriff's Office, MA | Official Website and the agency that reports for Cambridge (filed by the FBI as Cambridge Police Department) keep the arrest records in and around Cambridge: the report and the booking record of each arrest stay with the agency that made it, separate from the court file and from the state repository.
The FBI's agency list also places 12 campus police departments, one state agency and one state police unit in Middlesex County (the arrest records guide names each one); each keeps the records of its own arrests.
Together, the 51 agencies in Middlesex County with all twelve months of 2025 on file reported 15,399 arrests to the FBI that year; how each case ended is in the court file, not in the arresting agency's.
The agencies and their counts, year by year, are in Cambridge arrest records.
