Iranian President Mahmoud Ahmadinejad tapping Ahmad Vahidi for the post is "an affront to Argentine justice and the victims of the terrorist attack" on the Jewish community centre, the Foreign Ministry said in a statement.
News of the nomination was received "with grave concern and deserves the most energetic condemnation of the Argentine government," it said.
In 2007, Interpol issued a warrant for the arrest of Vahidi, a former head of Al Quds, an elite unit of Iran's Revolutionary Guard.
The July 9, 1994 bombing levelled the seven-floor Argentine Jewish Mutual Association building in Buenos Aires, killing 85 people and wounding 300.
