Baroness Kathleen Annie Pannonica de Koenigswarter (née Rothschild; 10 December 1913 – 30 November 1988) was a British-born jazz patron and writer. She was a leading patron of bebop music. She was a scion of the prominent Rothschild international financial dynasty.

Kathleen Annie Pannonica Rothschild was born in December 1913, in London, the youngest daughter of Charles Rothschild and his wife, Hungarian baroness Rozsika Edle von Wertheimstein, daughter of Baron Alfred von Wertheimstein of Transylvania. She was born into a branch of the wealthiest family in the world at the time. Her paternal grandfather was Nathan Rothschild, 1st Baron Rothschild. She grew up in Tring Park Mansion as well as Waddesdon Manor, among other family houses. The name "Pannonica" (shortened to "Nica" as a nickname) derives from Eastern Europe's Pannonian plain. Her friend Thelonious Monk reported that she was named after a species of butterfly her father had discovered, although her great-niece has found that the source of the name is a rare kind of moth, Eublemma pannonica. She was a niece of Walter Rothschild, the 2nd Baron Rothschild, and her brother Victor Rothschild became the 3rd Baron Rothschild. (According to thepeerage.com, she was granted the rank of the daughter of a baron on 15 March 1938.) Her elder sister Dame Miriam Rothschild was a distinguished scientist and zoologist.

In 1935 she married French diplomat Baron Jules de Koenigswarter, later a Free French hero. They lived together in a château in north-west France. She worked for Charles de Gaulle during World War II. The couple separated in 1951 and she moved to New York City, permanently renting a suite at 995 Fifth Avenue, and leaving behind five children. As a result of their separation, Koenigswarter was disinherited by her family, the Rothschilds. The couple eventually divorced in 1956. In 1958, she purchased a house with a Manhattan skyline view, originally built for film director Josef von Sternberg, at 63 Kingswood Road in Weehawken, New Jersey. Koenigswarter died in 1988, aged 74. By her first husband, she had five children, two grandchildren, and four great-grandchildren.
