A number of social media popularity and engagement metrics have been collated by social media leaderboard starcount.com, which put the Team GB diver at the top of the ranking.
Towards the end of the Games and following his bronze medal win, Daley surged past record-breaking gold medallists Michael Phelps and Usain Bolt to win the 'most popular' accolade.
Despite Daley coming third in Twitter's own figures from the Games, he pipped his Olympic rivals in starcount's data.
"Before he had even earned a medal this games, the photogenic Plymouth teenager had marked himself out as a star, hitting 1m Twitter followers after the first week of the games - thanks partly to controversy around a Twitter troll," starcount said.
"But Tom's social popularity has exploded again this weekend, as an anxious nation watched him triumph to a bronze in the nerve-wracking men's diving finals."
The company continued: "It sees Tom achieve an extraordinary 820k Facebook Fans and 1.2m Twitter followers through the course of the games, as well as become one of the most talked-about athletes on social media.
"The extra boost is enough to push Tom past both Phelps and Bolt, whose higher medal count is not enough to match his performance outside the arena, and confirms Tom as the ultimate social media Gold medallist for London 2012."
