A Comprehensive Guide to Mask Mandates in Missouri

The coronavirus global pandemic has transformed the way we live our lives, making social distancing, working from home, and wearing a mask the norm.

According to the CDC, wearing a mask out in public can protect you and your community by preventing COVID-19 respiratory droplets from traveling into the air and infecting others.

Most state Governors have issued mandatory mask requirements. Only 12 states – including Missouri – have not issued any statewide mask mandates.

(The New York Times provides interactive maps of COVID-19 restrictions and mask mandates in all 50 states.)

So what are the mask requirements in the state of Missouri? The answer depends on where you live. 

Missouri Governor Mike Parson has not issued a statewide mask mandate and left the decision to issue ordinances requiring face coverings up to local governments.

A mask ordinance can either be issued by a county or city – usually through the City Council or Board of Aldermen.

Below is a comprehensive list of county wide mask mandates across Missouri as of May 4, 2021. Note that ordinances can be issued by either a city or county, so it’s best to check both. For example, St. Louis County’s ordinance applies to all 88 municipalities within the county.
