Swimming

Five swimmers competed for Belgium at the 1912 Games. It was the third time the nation had competed in swimming, a sport in which Belgium had competed each time the country appeared at the Olympics.

None of the Belgian swimmers advanced to the finals in their individual events; two reached the semifinals.

Water polo

Belgium made its third Olympic water polo appearance in 1912, having competed both times the country had sent athletes to the Olympics previously. After taking the silver medals in 1908 and 1900, the Belgians were only able to win a bronze at these Games.

Belgium had the misfortune of meeting eventual gold medalists Great Britain in the quarterfinals, though this misfortune was mitigated by the use of the Bergvall System in the tournament (giving Belgium an opportunity to take silver even after this defeat). The Belgian squad gave the British side the greatest challenge the latter faced all tournament, taking the match into extra time before falling. In the repechage rounds, the Belgians defeated both of the other quarterfinal losers in turn. They then beat the losing finalist Austrians to set up a match against Sweden for the silver and bronze medals. This was the fifth match of the tournament for Belgium (the most of any team—the Belgians were the only side to play every other team in 1912), and the Swedes proved too much and defeated Belgium 4–2.

Greco-Roman

Belgium sent a single wrestler in 1912. It was the nation's second Olympic wrestling appearance, with the nation not having competed in the Olympics in 1896 or 1904 and wrestling not having been on the programme in 1900. Gerstmans, competing in the heavyweight class, lost his first two matches and was quickly eliminated.
