Lady Constance Stewart-Richardson (née Mackenzie; later Matthew; 6 April 1882[1] – 24 November 1932) was a British dancer and author.

Her paternal grandparents were George Sutherland-Leveson-Gower, 3rd Duke of Sutherland, and Anne Hay-Mackenzie, 1st Countess of Cromartie.

In 1904, Constance married Sir Edward Austin Stewart-Richardson, 15th Baronet (1872–1914) and bore him two sons.

[3] In 1910 her semi-clad dancing for the "shilling seats" of theatres incurred the displeasure of Edward VII, who considered it unsuitable behaviour for a noblewoman, and she was barred from Court – which constituted social death.

She went on to marry (in 1921 in London) Mr Dennis Leckie Matthew, an ex-guards officer who had spent several years in Chile pre-1914 observing German activities in South America for the British Government.
