The Community Security Trust has raised well over £3.5 million from a digital fundraising drive, smashing its initial target in under 24 hours.
Its appeal, Together We Protect, attracted more than 6,200 donations, with a group of donors matching all contributions.
The charity, which protects communities and monitors antisemitism, has said it needs to raise £2 million annually each year to continue its work.
Dame Margaret Hodge, broadcaster Eamonn Holmes and actresses Maureen Lipman and Tracy-Ann Oberman were among the appeal supporters.
