The honour recognises political and public service and was bestowed upon the Labour politician, 54, by King Charles.
Sir Sadiq has been Mayor of London since 2016 and was re-elected as mayor of the capital in both 2021 and 2024, making him the first London mayor to win a third term.
Following the announcement of the knighthood in the New Year Honours list, Sir Sadiq said: 'I am truly humbled to have received a knighthood in the King's New Year Honours.'
