Daisy, Princess of Pless (Mary Theresa Olivia; née Cornwallis-West; 28 June 1873 – 29 June 1943), was a noted society beauty in the Edwardian period.
Born Mary Theresa Olivia Cornwallis-West at Ruthin Castle in Denbighshire, Wales, she was the daughter of Col. William Cornwallis-West (1835–1917) and his wife, Mary "Patsy" FitzPatrick (1856–1920).  Her father, born William West, was a great-grandson of John West, 2nd Earl De La Warr. Her mother was a daughter of Reverend Frederick FitzPatrick and Lady Olivia Taylour, herself daughter of the 2nd Marquess of Headfort.
On 8 December 1891, in London, she married Hans Heinrich XV, Prince of Pless, Count of Hochberg, Baron of Fürstenstein (1861–1938), one of the wealthiest heirs in the German Empire, becoming hostess of Fürstenstein Castle and Pless Castle in Silesia.
They had three children:
- Hans Heinrich XVII, 4th Prince of Pless (1900–1984)
- Alexander, 5th Prince of Pless (1905–1984)
- Count Bolko Konrad Friedrich of Hochberg (1910–1936)
During her marriage Daisy, known in German as the Fürstin von Pless, became a social reformer and militated for peace with her friends William II, German Emperor and King Edward VII of the United Kingdom. During World War I she served as a nurse.
Hans Heinrich married as his second wife, at London on 25 January 1925, Clotilde de Silva y González de Candamo (1898–1978). This marriage produced two children, and was annulled in 1934. Subsequently Clotilde married her stepson, Bolko, and was the mother of Daisy's and Hans Heinrich's only grandchildren.
Daisy's brother George in 1900 married Jennie Churchill, the mother of Winston Churchill, as his first wife, and after their divorce married in 1914 Mrs. Patrick Campbell, the actress, as his second. Her sister, Constance, married in 1901 Hugh Grosvenor, 2nd Duke of Westminster, and after their divorce she married in 1920 James FitzPatrick Lewes.
Daisy, Princess of Pless, died in 1943 in relative poverty at Waldenburg, today Wałbrzych, Poland.
