Mohammed Yousef el-Magariaf or, as he writes on his official website, Dr. Mohamed Yusuf Al Magariaf, is a Libyan politician who served as the President of the General National Congress from its first meeting in August 2012 until his resignation in May 2013. In this role he was effectively Libya's de facto head of state, until his resignation in May 2013.

Elections for a General National Congress (GNC) were held in Libya on 7 July 2012, having been postponed from 19 June. They were the first elections since the overthrow and death of longtime ruler Muammar Gaddafi a year earlier, the first free national elections since 1952, and only the second free national elections since Libya gained independence in 1951.
