Sussex County Sheriff's Office (New Jersey)

The Sussex County Sheriff's Office is the principal law enforcement agency of Sussex County, New Jersey in the United States. Established in 1753 with the formation of the county, the sheriff's office is based in the county seat of Newton, New Jersey. The law enforcement agency's jurisdiction includes overseeing security at the county's courthouse facilities, operation a county jail (the Keogh-Dwyer Correctional Facility) and is responsible for civil processes including serving court documents (summons and complaints, various writs, subpoenas and other orders of the court), processing foreclosures, and conducting sheriff's sales.

The sheriff's office is led by an sheriff who is elected to office by the county's voting electorate. The position is mandated in each of the state's county by the New Jersey State Constitution and is one of three "constitutional officers" (the other's being County Clerk and County Surrogate). The current sheriff is Michael F. Strada, a former police officer with the Mount Olive Township Police Department, who is currently serving his second three-year term.
