The Federal Bureau of Investigation (FBI) is a leading law enforcement agency in the United States, operating under the jurisdiction of the Department of Justice. It serves as both an intelligence and security organization, with a mission to protect and defend the United States against terrorist and foreign intelligence threats, uphold and enforce the criminal laws, and provide leadership and criminal justice services to federal, state, municipal, and international partners. Established in 1908 by Attorney General Charles Bonaparte as the Bureau of Investigation, the FBI has grown into one of the most influential and iconic law enforcement agencies globally.

Its headquarters, known as the J. Edgar Hoover Building, is located in Washington, D. C.

It was named after the Bureau's longtime director who served from 1924 until his death in 1972. The FBI's main service offering lies in its core competencies of investigation, intelligence gathering, and providing support to law enforcement agencies. It conducts investigations into various crimes of national significance, including terrorism, cybercrime, organized crime, white-collar crime, and civil rights violations.

Additionally, the FBI plays a crucial role in collecting and analyzing intelligence through its intelligence divisions and maintains a robust network of field offices spread across the United States. On a global scale, the FBI collaborates with international partners through its Legal Attaché program, which places agents in embassies and consulates worldwide. This enables the Bureau to establish strong partnerships and exchange information with foreign law enforcement and intelligence agencies.

While it does not have international subsidiaries or joint ventures, the FBI maintains close cooperation with counterparts across the globe to combat transnational criminal activities and address global security threats. In terms of market position and global sales, the FBI does not operate as a commercial enterprise. Rather, it functions as a government agency financed by taxpayer funds.

Competitors in the law enforcement and intelligence sector include agencies like the Drug Enforcement Administration (DEA), Central Intelligence Agency (CIA), and Immigration and Customs Enforcement (ICE). The FBI's history is marked by various significant events, achievements, and changes in strategy. One notable milestone was the establishment of the FBI Laboratory in 1932, which remains a critical component of the Bureau's operations, providing forensic analysis and scientific support for investigations.

Another pivotal moment was the enactment of the USA PATRIOT Act in response to the 9/11 attacks, granting the FBI expanded surveillance and intelligence-gathering powers. As of the latest updates, the FBI continues to play a vital role in safeguarding national security and upholding the rule of law. It has been actively involved in combating cyber threats, countering terrorism, and addressing issues such as public corruption.

In recent years, the Bureau has faced increased scrutiny and challenges related to protecting civil liberties amidst the evolving nature of security threats. Nonetheless, the FBI remains an integral institution in maintaining law and order within the United States
