JFIU stands for the Joint Financial Intelligence Unit. The Unit was set up in 1989 to receive reports about suspicious financial activity made under the provisions of the Drug Trafficking (Recovery of Proceeds) Ordinance (DTROP) and, since 1995, the Organized and Serious Crimes Ordinance (OSCO). After the enactment of United Nations (Anti-Terrorism Measures) Ordinance (UNATM) in 2002, the Unit also receives suspicious transaction report related to terrorist property.

JFIU, as the name implies, is jointly run by staff of the Hong Kong Police Force and the Hong Kong Customs & Excise Department. The Unit is based in Police Headquarters, Arsenal Street, Wanchai. Full contact details can be found in the section "Contact Us".

JFIU does not investigate suspicious transactions. The role of the Unit is to receive, analyse and store suspicious transactions reports (STRs) and to disseminate them to the appropriate investigative unit. Typically, STRs will be passed to either the Narcotics Bureau or the Organized Crime & Triad Bureau of the Hong Kong Police Force, or the Customs Drug Investigation Bureau of the Hong Kong Customs & Excise Department.
