The 2020–21 Malaysia Government Movement Control Order (Malay: Perintah Kawalan Pergerakan Kerajaan Malaysia), commonly referred to as the MCO or PKP, was a series of national quarantine and cordon sanitaire measures implemented by the federal government of Malaysia in response to the COVID-19 pandemic in the country starting on 18 March 2020. The orders have been commonly referred to in local and international media as "lockdowns". MCO measures encompassed restrictions on movement, assembly and international travel, and mandated the closure of business, industry, government and educational institutions to curb the spread of SARS-CoV-2, the virus that causes COVID-19.
