In the second round of the singles competition at the London 2012 Olympics, Raonic lost to French player Jo-Wilfried Tsonga 3–6, 6–3, 23–25, breaking three Olympic tennis records. The match holds the records for the most games played in a best-of-three sets match (66 games) and the most games played in a single set (48 games) in Olympic history. At the time, it was the longest Olympic match by time played (3 hours 57 minutes), but this record was broken three days later in the semifinal match between Roger Federer and Juan Martin del Potro (4 hours 26 minutes).
