National Security Council Act 2016 () is a Malaysian law that "provide for the establishment of the National Security Council, the declaration of security areas, the special powers of the Security Forces in the security areas and other related matters". The Malaysian government claimed that this Act is intended to strengthen the government's ability to address increasing threats to the nation's security, including threats of violent extremism. Its bill was introduced into parliament by Shahidan Kassim on 1 December 2015. It was passed by the Dewan Rakyat (House of Representatives) on 3 December 2015, and the Dewan Negara (Senate) on 22 December 2015 without amendment.
The Act was deemed to have received royal assent on 18 February 2016 in pursuant to Clause 4A of Article 66 of the Federal Constitution, where a bill is automatically deemed to have been assented and becomes law if the Yang di-Pertuan Agong (King) did not give his assent within 30 days after the bill was presented to him. This Act is thought to be the first ever Act of Parliament in Malaysia to become law in this manner without the express assent of the monarch.
The Act has faced considerable consideration from human rights groups and other organisations both within Malaysia and internationally. Before the bill passed the Senate, the European Parliament passed a resolution calling for the Bill's withdrawal.
The National Security Council Act 2016, in its current form (7 June 2016), consists of 7 Parts containing 44 sections and no schedule (including no amendment).
