The Order of Olga (Württemberg) (German: Olga-Orden) was created by Karl I, King of Württemberg, on 27 June 1871, to honor his queen consort, Grand Duchess Olga Nikolaevna of Russia.

Its primary purpose was to honor women who cared for wounded soldiers in the Franco-Prussian War of 1870 – 1871.

The insignia was a cross of silver with the interlocking cipher of the King Karl and Queen Olga on the obverse and the years 1870-71 on the reverse.

Men, including the king, wore it from the buttonhole of his coat or as a military medal, while ladies wore it suspended form a large bow on their left breast.

This decoration was, incidentally, also given primarily to women, but was not part of the Order of Olga.
