Two of the 15 people arrested on Wednesday during disturbances in central Athens were on Thursday charged with felonies including disturbing the peace and covering their faces during a public protest.
A prosecutor charged another 11 detainees with misdemeanors and two more will have to appear in a juvenile court as they were minors.
The arrests were made when protesters clashed with police near Parliament.
Thousands of people had descended on the city center to attend a demonstration by the so-called Indignant movement and rallies by labor unions that were taking part in a general strike.
Four of the 81 policemen injured during the clashes remained in the hospital on Thursday.
