Ida-Viru County (Estonian: Ida-Viru maakond, Russian: И́да-Ви́руский уезд), or Ida-Virumaa, is one of 15 counties of Estonia. It is the most north-eastern part of the country. The county contains large deposits of oil shale - the main mineral mined in Estonia. As oil shale is used in thermal power plants, the earth in Ida-Viru contains most of Estonia's energy resources. The capital of the county is the town of Jõhvi which is administratively united with the Jõhvi Parish. 149 483 people live in Ida-Viru County – constituting 12.6% of the total population in Estonia (as of January 2014).
The County Government (Estonian: Maavalitsus) is led by a Governor (Estonian: maavanem), who is appointed by the country's government for a term of five years. Since August 2004 the governor's position is held by Ago Silde. The current governor of Ida-Viru county is Andres Noormägi.
