The European Union says Turkey's measures against the education system, the judiciary and the media following the failed coup are "unacceptable".
In a statement, High Representative Federica Mogherini and Commissioner Johannes Hahn said they were "concerned" by Turkey's decision to declare a state of emergency.
The move gives Turkey's leaders "far-reaching powers to govern by decree".
Thousands of people have been sacked or arrested following the failed coup.
The two senior EU officials urged President Recep Tayyip Erdogan to respect the rule of law, rights and freedoms.
And they also warned Turkey over its decision to suspend the European Convention on Human Rights, saying it must stick to the conditions by which a suspension is permitted.
Turkey is a candidate to join the EU, but its accession talks have progressed extremely slowly.
