Thousands of people joined Olympians in the centre of London in October to celebrate the success of Rio 2016.
It was Great Britain's most successful away Olympics with the team winning 27 gold medals, and 67 medals in total. The Paralympics team also came back victorious, with an incredible 147 medals, 64 of them gold.
The crowds heard from some of the stars of Rio including Adam Peaty, Tom Daley and the hockey team goalkeeper Maddie Hinch.
London Mayor Sadiq Khan was on hand to congratulate the team. He said: "Team GB and Paralympics GB, you smashed it. We are now a sporting superpower and I want to say congratulations and well done."
To bring the celebrations to a close, The Vamps were on hand to serenade the crowd and the athletes. The event was followed by a reception at Buckingham Palace for the athletes.
