The Harford County Detention Center is a medium-security detention center located at 1030 Rock Spring Rd Bel Air, MD which is operated locally by the Harford County Sheriff's Office and holds inmates awaiting trial or sentencing or both. Most of the sentenced inmates are here for less than two years. Harford County accepts inmates from surrounding towns, municipalities, the US Marshal's Service and the Bel Air Police Department who do not have their own long-term lock-up.

The predecessor to the Harford County Detention Center was the jail. The original jail was constructed in 1791, portions of which are still standing. This jail consisted of three floors, each with six double-bunked cells per floor, one cell for females, and one for juveniles. Meals were prepared on-site by the Sheriff’s wife and served on a small metal tray. The old jail served as a pre-sentence holding facility only. During the mid-1960s, the agency had three jailers, who also served as police radio operators. Religious and family visits were the only services offered at the time.

The primary purpose of the Detention Center is to provide care, custody and safety of the prisoners and staff, it also offers a variety of programs to the inmate. These programs provide inmates an opportunity to maintain and improve their physical, emotional, and psychological wellbeing upon re-integration into the Harford County community.

The Harford County Detention Center opened in 1973 with a capacity of 100 inmates. The latest expansion was completed in 2012, which added 288 beds to the facility for a total capacity of 762.
