Clara Marie Wæver (7 April 185–18 August 1930) was a Danish embroiderer who in 1890 opened a successful business in Copenhagen.
Recognized for its high quality, it also provided instruction and training in needlework for young women.
In 1903, Wæver enhanced her wares by acquiring the studio where Constantin Hansen's daughters, Kristiane Konstantin-Hansen and Johanne Bindesbøll, had worked, including all its artworks, models and designs.
In 1917, she transferred ownership of the business which then became known as Eva Rosenstand Clara Wæver.
It survives today in the centre of Copenhagen as Eva Rosenstand.
