The murder attracted worldwide attention with tributes and memorials for Cox being made with condemnation of Mair. A personal friend, Canadian MP Nathan Cullen paid tribute to Cox in the House of Commons of Canada. Canadian Prime Minister Justin Trudeau, former US Secretary of State Hillary Clinton, the then US Secretary of State John Kerry and former US Representative Gabby Giffords, who was wounded in an assassination attempt in 2011, were among international politicians who sent messages of condemnation and sympathy in the aftermath of her killing. Cox's husband issued a statement urging people to "fight against the hatred that killed her."
