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 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 Riho Breivel.
