The Alameda County Sheriff's Office (ACSO) is a law enforcement agency serving Alameda County, California. ACSO is accredited through the Commission on Accreditation for Law Enforcement Agencies (CALEA), the American Correctional Association (ACA), National Commission on Correctional Health Care (NCCHC) and the California Medical Association (CMA).
As of 2008, ACSO has approximately 1500 positions, over 1000 of which are sworn peace officers.
ACSO is charged with:
- Providing security to the Consolidated Superior Courts
- Operating the Coroner's Bureau
- Operating a full-service crime laboratory
- Operating a county jail and detention center
- Conducting a basic academy pursuant to Police Officer Standards and Training (POST) requirements
- Performing Civil Process
- Operating the County Office of Emergency Services
- Providing Fish and Game enforcement
- Operating a Marine Patrol Unit in the San Francisco Bay waters
- Providing patrol and investigative services to the unincorporated areas of Alameda County
- Pursuant to contractual agreements, providing patrol and investigative services to the city of Dublin, Peralta Community College District, Oakland-Alameda County Coliseum complex, Oakland International Airport, Highland County Hospital, Social Services, and to the Alameda-Contra Costa Transit District
ACSO operates two detention facilities. The Santa Rita Jail, located in Dublin, CA, is the primary facility that houses most people arrested or convicted of crimes in Alameda County. The Glenn Dyer Detention facility, also known as the North County Jail, houses a smaller number of inmates and is located in downtown Oakland, directly adjacent to the Wiley W. Manuel court building in which the majority of the county's criminal calendar is initially heard.
Training and exercises
ACSO operates a police academy and training exercises for the greater law enforcement community in the Bay Area.
Sheriff Gregory J. Ahern created Urban Shield in 2007 in order for law enforcement tactical teams to become better prepared to respond to any act of terror or major critical incident. The purpose was also to established better relationships between first responders that included law enforcement, fire personnel and medical personnel. Urban Shield has grown into a comprehensive, full-scale regional preparedness exercise assessing the overall Bay Area UASI Region's response capabilities related to multi-discipline planning, policies, procedures, organization, equipment and training. Urban Shield continues to test regional integrated systems for prevention, protection, response and recovery in our high-threat, high-density urban area. The exercise evaluates our existing level of preparedness and capabilities, identifying not only what we do well, but areas in need of improvement. The previous years' After Action Reports are referenced and utilized to assist in prioritizing upcoming expenditures possible for the region, so the region may become more prepared for any type of critical event or incident in our area.
The overarching goals of Urban Shield include striving for the capability to present a multi-layered training exercise to enhance the skills and abilities of regional first responders, as well as those responsible for coordinating and managing large-scale events. Urban Shield is implemented to identify and stretch regional resources to their limits, while expanding regional collaboration and building positive relationships. In addition, this exercise provides increased local business and critical infrastructure collaboration. Urban Shield challenges the skills, knowledge and abilities of all who participate. It not only improves regional disaster response capabilities, but provides a platform for national and international first responders, as well as the private sector, to work efficiently and effectively together when critical incidents occur. 
Urban Shield is supported by the Bay Area Urban Area Security Initiative. Since 2012, the Bay Area UASI tests portions of the Regional Catastrophic Preparedness Grant Program as part of the full scale readiness exercise, such as the regional mass fatality plan.
Hosted by ACSO, Urban Shield is the largest urban full scale readiness exercise in the United States. Police, Fire, Hazmat, EMS and EOD teams from all over the nation train in multiple scenarios over a continuous 50-hour exercise. Scenarios included the first year were an active shooter on the UC Berkeley campus, airplane hijacking, maritime interdiction and a 20-mile hike.
Numerous first responders from around the county and the world have participated in or observed Urban Shield. Boston Police Commissioner Edward F. Davis credited Urban Shield with helping prepare the Boston Police Department for their response to the Boston Marathon Bombing
Eden Township substation
ACSO operates a crime laboratory that is accredited by the American Society of Crime Laboratory Directors. The Crime Lab, located at the Eden Township substation, receives and analyzes evidence from law enforcement agencies throughout Alameda County. The Crime Lab has capabilities in controlled substance analysis, latent fingerprint recovery, ballistics, tool mark identification, and DNA extraction and analysis. Crime Lab staff can also serve as crime scene investigators upon request by law enforcement agencies in the county.
ACSO operates the Coroner's Bureau in downtown Oakland. Coroner's pathologists, deputy sheriffs, forensic death investigators, and sheriff's technicians assist law enforcement agencies to determine the type and manner of death of persons in Alameda County. They also make contact with next of kin, and seize and protect decedents' assets when needed. If next of kin cannot be located, they decide when to refer the case to the Public Administrator.

In early 2013, Sheriff Gregory Ahern made a controversial proposal to purchase an Unmanned Aerial Vehicle (UAV). Sheriff Ahern was one of the first law enforcement officers in California to request a UAV. Opponents petitioned the purchase, and formed the organization Alameda County Against Drones (ACAD). The controversy generated nationwide interest. The Board of Supervisors did not approve the purchase in 2013.
In 2013, the Urban Shield training program was controversially held on the second anniversary of the removal of Occupy Oakland from Frank Ogawa Plaza. Some community activists believed that Urban Shield was part of a militarization of civilian peace officers to limit free speech and assembly, and claimed that Urban Shield was a forum for the arms industry.
With the June 2014 election, a group called "Elections for the People" have been concerned that for many decades the position of Sheriff, while elected, has not been a contested election. The current Sheriff Ahern was selected by the prior Sheriff Plummer, and has run twice, unopposed. The 2012 salary for the Sheriff of Alameda was over $547,000.00; which includes a base salary of $267,871, and other benefits and payments.
During the Free Speech Movement riots of the 1960s, Alameda County Sheriff deployed several squads of deputies. Clad in light blue jumpsuits, they quickly became known by anti-government protesters as "The Blue Meanies."
In November 2010, October and November 2011, and January 2012, Alameda County Sheriff's Deputies were requested by the Oakland Police Department and supplied by the Sheriff to assist at protests.

The municipal police departments provide routine law enforcement services for those cities, with ACSO providing corresponding services for unincorporated regions of Alameda County and the city of Dublin.
