CORE (Community Organized Relief Effort) (formerly J/P Haitian Relief Organization) is a non-profit organization founded by actor Sean Penn in response to the January 12, 2010 earthquake in Haiti. The organization was founded in 2010 and changed its name in 2019 to receive contracts and donations to work globally. In March 2020, CORE began administering free COVID-19 tests in the U.S. amid the COVID-19 pandemic.
