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

The nation has competed at every Summer Olympic Games since its official debut in 1908.

Notable Finnish athletes included the defending champion Satu Mäkelä-Nummela in women's trap shooting, and Olympic bronze medalist Tero Pitkämäki in men's javelin throw.

Badminton player Anu Nieminen, and swimmer Hanna-Maria Seppälä, who finished fourth in the women's freestyle event, made their fourth Olympic appearance as the most experienced athletes.

Several Finnish athletes who reached finals missed out on the medal standings including Pitkämäki, and taekwondo jin Suvi Mikkonen.
