On Twitter, the search engine's CEO Sundar Pichai also paid tribute to the monarch.
"Sending our deepest condolences to the people of the UK and around the world mourning the passing of Queen Elizabeth II," he tweeted.
"Her steadfast leadership and public service have been a constant through many of our lifetimes. She will be missed."
The 96-year-old died "peacefully" at Balmoral Castle in Scotland, after a record-breaking 70-year reign on the throne. On Thursday, Prince Charles was seen rushing to his mother's bedside, followed by Prince William, Prince Edward, Princess Anne, Prince Andrew and Prince Harry.
Since her passing, tributes have flowed in from all over the world. Mourners flocked to Buckingham Palace in the hours after the news broke.
Adorned in the Union Jack, supporters were seen singing 'God Save the Queen' as a double rainbow appeared in the sky.
The royal family have confirmed that the newly installed King and Queen Consort will remain at Balmoral Castle, before returning to London on Friday.
King Charles III will then meet the Ascension Council at 10am at St James's Palace where he will officially be proclaimed as King.
