Princess Ida Matilda Adelaide of Schaumburg-Lippe (Bückeburg, 28 July 1852 – Schleiz, 28 September 1891) was the consort of Heinrich XXII, Prince Reuss of Greiz from 1872 until her death.

She was the mother of Hermine Reuss of Greiz, second wife of Wilhelm II, the last German Emperor.

She was a daughter of Adolf I, Prince of Schaumburg-Lippe and his wife Princess Hermine of Waldeck and Pyrmont.

Despite their high birth, Ida and her siblings were brought up very simply; one report said they "knew more about the kitchen than many women of lower degree".

[1] On 8 October 1872, Ida married Heinrich XXII, the reigning Prince of Reuss since he came of age in 1867.
