The search engine giant has today displayed a video animation to pay tribute to the late Queen frontman, nearly 20 years after he tragically passed away.
The 'Google doodle' sees a cartoon version of Mercury perform one of Queen's most famous hits 'Don't Stop Me Now' above the search box.
The animation is available to Google users outside of the US, while American users will have a belated birthday doodle as Mercury's actual birthday falls on Labour Day.
Mercury's family, friends, guests and celebrities are to descend on the Savoy Hotel in London tonight to celebrate the occasion and to raise funds for the Mercury Phoenix Trust.
The Mercury Phoenix Trust was set up by fellow Queen members Brian May and Roger Taylor together with their manager Jim Beach following Mercury's death, to raise funds to help fight HIV AIDS worldwide.
Mercury's birthday will also act as a key focal point for the Freddie For A Day campaign, which was launched last year through the global Queen fanbase.
Fans from all over the globe will dress up as the star for a day to gain sponsorship, which will go towards the Mercury Phoenix Trust.
Queen have previously announced plans to reissue their last five studio albums on September 5 in memory of Mercury.
