Its county seat is Houston. The Harris County Sheriff's Office has approximately 3,500 employees and is the largest sheriff's office in the state of Texas and the sixth largest in the nation.

In Texas, sheriffs and their deputies are fully empowered peace officers with county-wide jurisdiction and thus, may legally exercise their authority in unincorporated and incorporated areas of their county; they primarily provide law enforcement services for only the unincorporated areas of a county, while yielding to municipal police or city marshals to provide law enforcement services for the incorporated areas. Sheriffs and their deputies also have statewide warrantless arrest powers for any criminal offense (except certain traffic offenses) committed within their presence or view. They also may make arrests with a warrant anywhere in the state. In an emergency, sheriffs along with mayors and district judges are empowered by state law to call forth the National Guard to preserve the peace. The jurisdiction of the Harris County Sheriff's Office often overlaps with several other law enforcement agencies, among them the Texas Highway Patrol, the eight Harris County Constable Precincts, and several municipal police agencies including the city of Houston Police Department. The duties of a Texas sheriff generally include keeping the county jail, providing bailiffs for the county and district courts within his county and serving process issued by said courts, and providing general law enforcement services to residents. The current sheriff of Harris County is Ed Gonzalez, elected in 2016 and has been in office since January 1, 2017.
