Congo competed at the 2012 Summer Olympics in London, United Kingdom from 27 July to 12 August 2012.

Comité National Olympique et Sportif Congolais sent the nation's largest delegation after the 1992 Summer Olympics in Barcelona.

Among the athletes, swimmer Emile Bakale and table tennis player Suraju Saka competed only at their second consecutive Olympics.

Sprinter Lorène Bazolo, on the other hand, was the nation's flag bearer at the opening ceremony.

Congo has gained two "Universality places" from the FINA.
