There will likely be further tributes across the weekend in Monza, though no confirmation has yet been released.
F1 teams, drivers and officials gathered in the pitlane ten minutes before the opening session, which is scheduled for 2pm BST.
Ahead of the Italian GP, Sir Lewis Hamilton paid an emotional tribute.
“How do you find the words to describe the loss of Her Majesty The Queen?” wrote the seven-time world champion on Instagram.
“She was truly an iconic leader, an inspiration and a reassuring presence for most, if not all, of our lives.
“Since the sad news yesterday, I’ve been reflecting on her incredible life. She was a symbol of hope for so many and she served her country with dignity, dedication and kindness.
“She was truly like no other and I’m grateful to have lived during her time. Her legacy will be long-lasting and her passing deeply felt.”
Hamilton also received an MBE following his maiden world title win in 2008.
Reflecting on his investitures, Hamilton said: “I had the incredible honour of being able to spend time with her. It is something I’ll never forget.
“We talked about our shared love of dogs and she was incredibly generous with her time.
“I know the whole nation and many others around the world will be mourning her loss and my thoughts and prayers are with her family and all those close to her, who have lost a loved one. Rest in Peace.”
