A federal court decided to remove Juan Jose Galeano following allegations of irregularities in the investigation.
He has no right to appeal against the decision which has been broadly welcomed by families of the victims.
No-one has been charged over the bombing in 1994
No-one has ever been found guilty of the worst-such attack in Argentina, which killed 85 people.
The 1994 bombing of the Israeli-Argentine Mutual Association also left more than 200 people injured.
A young, well-respected investigating judge named Juan Jose Galeano was immediately put on the case, charged with tracking down the perpetrators.
He got off to a good start when a man alleged to have provided the van used in the bombing, Carlos Telleldin, was quickly arrested, followed by some 20 officers from the Buenos Aires provincial police.
But when a grainy black-and-white video showing Judge Galeano apparently offering Mr Telleldin $400,000 was broadcast on Argentine TV, the judge's methods were called into question.
Pablo Jacoby, the lawyer representing around 20 victims' families, filed an official complaint against the judge, accusing him of irregularities and demanding Mr Galeano be thrown off the case.
Now Mr Jacoby's wish has been granted.
He told the BBC the investigation would continue from where it had left off, adding that he hoped it would now be free from interferences.
