The Guardia di Finanza (Italian: [ˈɡwardja di fiˈnantsa]; G. di F. or GdF; lit. 'Financial Guard' or 'Financial Police') is an Italian militarised law enforcement agency under the Ministry of Economy and Finance.

The mission and institutional tasks of the Guardia di Finanza are stated in law 189 of 23 April 1959, and 68/2001 and are subdivided into priority ones (preventing, investigating and reporting financial evasions and violations, overseeing the compliance with the provisions of politico-economic interest and surveillance at sea for financial police purposes) and contribution ones (maintaining public order and safety, political-military defence of the borders and international antidrug operations).

The primary mission of the Guardia di Finanza is to protect the legal economy and the businesses operating in compliance with the law while ensuring that the Republic, the European Union, the regions, and the local governments can rely on a regular income and appropriate use of the resources meant for the community, and for supporting policies for economic and social revival and development.

Its activities are connected with the financial, economic, judiciary and public safety:

Interpol summarizes the Guardia di Finanza as

"a force with military status and nationwide remit for financial crime investigations and illegal drugs trafficking investigations".

Europol (the EU's law enforcement agency), summarizes this force as

"organized according to a military structure ... The tasks of the Guardia di Finanza consist of the prevention, search and denunciation of evasions and financial violations, the supervision of the observance of the provisions of political and economic interest and the surveillance at sea for financial police purposes. Therefore, the Guardia di Finanza is a police force with general jurisdiction over all economic and financial matters; it also contributes to the maintenance of order and public security and military defence along national borders."
