A Turkish high court ruled that access to YouTube should be restored in the country, following a block was imposed in late March.
Turkey's highest court has said the block violated laws governing freedom of expression. The local telecom authorities are orderd to lift the block.
Both Youtube and Twitter sites were blocked earlier this year after recordings of official meetings were leaked and widely circulated. One recording involved senior army officers discussing intervention in Syria and others supposedly revealed corruption among people close to Mr Erdogan.
The block on Twitter was lifted last month.
