The outdoor mixed doubles competition at the 1912 Summer Olympics was part of the tennis program for the games.

[1] The event was won by German pair Dorothea Köring and Heinrich Schomburgk.

The silver medalists were Sweden's Sigrid Fick and Gunnar Setterwall, while French team Marguerite Broquedis and Albert Canet took bronze.

Tennis was not a medal sport from 1928 to 1984, though there were demonstration events in 1968 (which included mixed doubles) and 1984 (which did not).

Germany's mixed doubles champions Dorothea Köring and Heinrich Schomburgk were the strongest players among a weak field.
