The Fiscal Information and Investigation Service (Dutch: Fiscale inlichtingen- en opsporingsdienst, FIOD) is an agency of the government of the Netherlands responsible for investigating financial crimes.

It is part of the Tax and Customs Administration, which itself falls under the responsibility of the Dutch Ministry of Finance.

The FIOD-ECD was formed when the FIOD and the ECD (Dutch: Economische Controledienst) were merged in 1999.
