Sadiq Khan received 1,206,034 votes
The Labour candidate beat Conservative Shaun Bailey after winning 55.2 per cent of the popular vote in the second round of voting.
Mr Khan said he would be a mayor for all Londoners and would not ignore the voices and concerns of those who did not vote for him.
“We all have a responsibility to do everything we can to build the bridges that bring us together rather than the walls that can only drive us further apart,” he said.
“This virus doesn’t care whether you live in London or Liverpool, whether you are a Brexiteer or a Remainer, or what you think it means to be woke.
“We are only defeating it by acting together and helping each other.”
Mr Bailey described running for Mayor as the “experience of a lifetime” and said he hoped Mr Khan would not “pass the buck” and would “live up to his responsibilities”.
He added: “My campaign gave a voice to people worried about their safety, about house prices, about an ever-rising cost of living.
“Together we shone a spotlight on issues that Sadiq Khan ignored.”
The Green Party’s Sian Berry came third while Liberal Democrat candidate Luisa Manon Porritt placed fourth.
In the London Assembly elections, Havering and Redbridge re-elected Conservative Keith Prince.
He beat out Labour’s Judith Garfield with 77,268 votes to 61,941.
