The '''Federal Bureau of Investigation''' ('''FBI''') is the domestic [[Intelligence agency|intelligence]] and [[Security agency|security]] service of the [[United States]] and [[Federal law enforcement in the United States|its principal federal law enforcement agency]]. An agency of the [[United States Department of Justice]], the FBI is a member of the [[United States Intelligence Community|U.S. Intelligence Community]] and reports to both the [[United States Attorney General|attorney general]] and the [[Director of National Intelligence|director of national intelligence]].<ref name="intel">{{cite web |url=http://www.intelligence.gov/mission/member-agencies.html |title=Our Strength Lies in Who We Are |website=intelligence.gov |access-date=August 4, 2014 |archive-url=https://web.archive.org/web/20140810180812/http://www.intelligence.gov/mission/member-agencies.html |archive-date=August 10, 2014}}</ref> A leading American [[counterterrorism]], [[counterintelligence]], and criminal investigative organization, the FBI has [[jurisdiction]] over violations of more than 200 categories of [[Federal crime in the United States|federal crimes]].<ref>{{cite web |url=https://www.fbi.gov/about/faqs/how-does-the-fbi-differ-from-the-drug-enforcement-administration-dea-and-the-bureau-of-alcohol-tobacco-firearms-and-explosives-atf |title=How does the FBI differ from the Drug Enforcement Administration (DEA) and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF)? |publisher=Federal Bureau of Investigation |access-date=November 2, 2017 |url-status=live |archive-url=https://web.archive.org/web/20170904013109/https://www.fbi.gov/about/faqs/how-does-the-fbi-differ-from-the-drug-enforcement-administration-dea-and-the-bureau-of-alcohol-tobacco-firearms-and-explosives-atf |archive-date=September 4, 2017}}</ref><ref name="quickfacts">{{cite web |url=https://www.fbi.gov/quickfacts.htm |title=Federal Bureau of Investigation – Quick Facts |publisher=Federal Bureau of Investigation |archive-url=https://web.archive.org/web/20111017083929/http://www2.fbi.gov/quickfacts.htm |archive-date=October 17, 2011}}</ref>

Although many of the FBI's functions are unique, its activities in support of [[national security]] are comparable to those of the British [[MI5]] and [[National Crime Agency|NCA]], the New Zealand [[Government Communications Security Bureau|GCSB]] and the Russian [[Federal Security Service|FSB]]. Unlike the [[Central Intelligence Agency]] (CIA), which has no law enforcement authority and is focused on intelligence collection abroad, the FBI is primarily a domestic agency, maintaining 56 [[List of FBI field offices|field offices]] in major cities throughout the United States, and more than 400 resident agencies in smaller cities and areas across the nation. At an FBI field office, a senior-level FBI officer concurrently serves as the representative of the director of national intelligence.<ref>[https://www.fbi.gov/news/testimony/fbi-budget-request-for-fiscal-year-2015 Statement Before the House Appropriations Committee, Subcommittee on Commerce, Justice, Science, and Related Agencies] ({{webarchive |url=https://web.archive.org/web/20160623212212/https://www.fbi.gov/news/testimony/fbi-budget-request-for-fiscal-year-2015 |date=June 23, 2016}}), Federal Bureau of Investigation, March 26, 2014</ref><ref>[https://www.washingtonpost.com/world/national-security/fbi-gets-a-broader-role-in-coordinating-domestic-intelligence-activities/2012/06/19/gJQAtmupoV_story.html "FBI gets a broader role in coordinating domestic intelligence activities"] ({{webarchive |url=https://web.archive.org/web/20170716094314/https://www.washingtonpost.com/world/national-security/fbi-gets-a-broader-role-in-coordinating-domestic-intelligence-activities/2012/06/19/gJQAtmupoV_story.html |date=July 16, 2017}}), ''[[The Washington Post]]'', June 19, 2012</ref>

Despite its domestic focus, the FBI also maintains a significant international footprint, operating 60 Legal Attache (LEGAT) offices and 15 sub-offices in [[List of diplomatic missions of the United States|U.S. embassies and consulates]] across the globe. These foreign offices exist primarily for the purpose of coordination with foreign security services and do not usually conduct unilateral operations in the host countries.<ref>[https://www.fbi.gov/about-us/international_operations/overview "Overview of the Legal Attaché Program"] ({{webarchive |url=https://web.archive.org/web/20160313042943/https://www.fbi.gov/about-us/international_operations/overview |date=March 13, 2016}}), Federal Bureau of Investigation.

These activities generally require coordination across government agencies.

The FBI was established in 1908 as the Bureau of Investigation, the BOI or BI for short. Its name was changed to the Federal Bureau of Investigation (FBI) in 1935.<ref>{{Cite web |url=https://www.fbi.gov/news/stories/2006/march/fbiname_022406 |title=A Byte Out of History – How the FBI Got Its Name |publisher=FBI |access-date=February 9, 2021 |archive-date=March 31, 2016 |archive-url=https://web.archive.org/web/20160331180657/https://www.fbi.gov/news/stories/2006/march/fbiname_022406 |url-status=live }}</ref> The FBI headquarters is the [[J.
