Freedom of Information Act may refer to the following legislations in different jurisdictions which mandate the national government to disclose certain data to the general public upon request:

• Freedom of Information Act 1982, the Australian act
• Freedom of Information Act (United States) of 1966
• Freedom of Information Act 2000, the UK act
• Freedom of Information (Scotland) Act 2002

Freedom of Information laws (FOI laws) allow access by the general public to data held by national governments. They establish a "right-to-know" legal process by which requests may be made for government-held information, to be received freely or at minimal cost, barring standard exceptions. Also variously referred to as open records, or sunshine laws (in the United States), governments are typically bound by a duty to publish and promote openness. In many countries there are constitutional guarantees for the right of access to information, but these are usually unused if specific support legislation does not exist.
