Mr Cameron said it had been a moving experience to be in Paris on Sunday for the solidarity marches and recalled seeing signs reading "JeSuisJuif" in the crowds.
"We should use the momentum of those great demonstrations to emphasise what we are in this country: a very successful multi-ethnic, multi-faith democracy."
Among the members of the Jewish delegation attending the annual meeting with the Prime Minister were Jewish Leadership Council chairman Mick Davis, Community Security Trust chairman Gerald Ronson and Board of Deputies president Vivian Wineman.
The meeting also discussed rising antisemitism in Britain, anti-Israel boycotts on university campuses, and the situation in the Middle East.
