The Prime Minister announced that the Government will increase funding for the Holocaust Educational Trust (HET) by an extra £300,000 a year.
The extra funds will allow more children to take part in the Trust's Lessons from Auschwitz Project, which allows students and teachers to visit the former Nazi concentration and death camp Auschwitz-Birkenau.
He also launched a new national Holocaust commission, which will set up a permanent Holocaust memorial in Britain.
Mr Cameron told the Trust's Appeal Dinner: “At a time when anti-Semitism is returning in some parts of mainland Europe, it is more important than ever that – as a whole country – we do everything possible to make sure that the memory of the Holocaust is preserved from generation to generation.
"The Holocaust Educational Trust are leading the way, and it is vital that they are supported.”
