Luxembourg competed at the 1912 Summer Olympics in Stockholm, Sweden.

It was the first official appearance at the modern Olympic Games for the nation, although it was later discovered that one Luxembourgish athlete competed in 1900.

Two athletes represented Luxembourg in the nation's Olympic debut.

Pelletier's 17th-place finish in the shot put was Luxembourg's best placement.
