The 2017 social unrest in French Guiana was a series of protests and strikes led by the "Collective of 500 Brothers" to highlight the issues of insecurity and infrastructure in French Guiana, France. It began on March 20, 2017 in Kourou, and spread all over French Guiana within a few days. Several international rocket and satellite launches were postponed, and March 28 saw the largest demonstration ever held in French Guiana.
