Authorities said four people were detained.
In footage posted on social media, protesters were seen lighting flares and chanting pro-Palestinian slogans in La Philharmonie concert hall in northern Paris as some audience members and security personnel tried to remove them.
''Every 10 to 20 minutes someone tried to ruin the concert," Israeli Embassy in Paris official Osnat Menache, who attended the event, told The Associated Press.
''The first flare - the person was holding it and he moved very fast in between the people."
At one point it fell on a chair very close to the orchestra.
The musicians eventually returned to the stage to finish the concert.
"I strongly condemn the actions committed last night during a concert at the Philharmonie de Paris. Nothing can justify them," Interior Minister Laurent Nunez said on X.
"I thank the personnel from the Paris police who enabled the rapid arrest of several perpetrators of serious disturbances inside the venue and contained the demonstrators outside. Four people have been placed in custody," he added.
The Paris prosecutor's office said three women and a man were in custody, on charges ranging from violence, destruction and organising an unauthorised protest.
Culture Minister Rachida Dati on X condemned the disruptions as going against the "fundamental rights of our Republic".
The Philharmonie said it had filed a criminal complaint.
A group of pro-Palestinian musicians and supporters issued an appeal last month to the director of the Paris Philharmonic to cancel the concert.
''To maintain this concert would be to contribute to Israel's impunity before international law; to instrumentalise classical music ... in the whitewashing of policies that for 75 years have denied the fundamental rights of the Palestinian people," the group said.
