Censorship in Myanmar (also called Burma) results from government policies in controlling and regulating certain information, particularly on religious, ethnic, political, and moral grounds. Freedom of speech and the press are not guaranteed by law. Many colonial-era laws regulating the press and information continue to be used. Until August 2012, every publication (including newspaper articles, cartoons, advertisements, and illustrations) required pre-approval by the Press Scrutiny and Registration Division (PSRB) of the Ministry of Information. However, the 2011–2012 Burmese political reforms signalled significant relaxations of the country's censorship policies and in August 2012 the Ministry of Information lifted the requirement that print media organisations submit materials to the government prior to publication. Burma ranked 151st of 179 nations in the 2012–2013 worldwide Press Freedom Index from Reporters Without Borders.

The Official Secrets Act was passed in 1923, which makes it unlawful for any person to possess classified information from the state. A decade later, the Burma Wireless Telegraphy Act was passed, criminalising possession of telegraphs without government permission. However, there were numerous publications in circulation during the colonial era, with a steady increase. In 1911, there were 44 periodicals and newspapers in circulation, and 103 in 1921. By the end of the 1930s, there were over 200 newspapers and periodicals in circulation, double the amount in 1921. Post-independence era Burma gained independence in 1948. The Constitution of the Union of Burma (1947) guaranteed freedom of expression, guaranteeing the "liberties of thought and expression". Two years later, the Emergency Provisions Act, which criminalised the spreading of false news knowingly and the slandering of civil servants and military officials was enacted. Despite the law, in the 1950s, Burma had one of the freest presses in Asia, with 30 daily newspapers (in Burmese,
