Starting the race from pole position, Leclerc made history with his victory as he became the first Monegasque driver to win on home soil in the F1 World Championship era.
Louis Chiron, another Monegasque racing driver, had won the third edition of the race back in 1931 before the official championship began in 1950.
This year’s race got off to a dramatic start with a violent crash on the opening lap for Sergio Perez and Haas duo Nico Hulkenberg and Kevin Magnussen brought out the red flag.
After the restart, Leclerc was able to hold onto his lead to win the race, with Oscar Piastri finishing second and Ferrari team-mate Carlos Sainz coming third.
The Grand Prix was criticised by many spectators for its lack of action, with the race marking the first time in F1 history that the top ten finished in the order they started.
Leclerc left fans stunned with his antics after the Grand Prix, as videos emerged on social media of the 26-year-old appearing to cycle home from the race.
Having just raced almost two and a half hours on the edge around a track as difficult and precise as Monaco, fans were quick to fire in some priceless reactions to Leclerc's choice.
“Faster than the cars went round Monaco,” said one fan.
“I couldn’t work out if this was after the party or straight after the race! He was cycling fairly well for someone who just had a massive party,” said another.
