The new measures targeted 32 individuals and two entities, and were largely aimed at lawmakers, judiciary officials and prison authorities accused of involvement in the repression, according to the EU's official journal.
Judges, prosecutors and senior prison officials were also included in the new sanctions over their involvement in alleged abuses.
The EU had already imposed sanctions on more than 70 Iranians over the crackdown on protestors, including the "morality police", Revolutionary Guard Corps commanders and state media.
