Eva Ekeblad (née De la Gardie; 10 July 1724 – 15 May 1786) was a Swedish agriculturist and salon hostess.

She discovered a method to make alcohol and flour from potatoes, significantly reducing Sweden's incidence of famine.

She signed her name as Eva Delagardie, retaining her maiden name as was customary in Sweden in the early 1700s, but she is most often referenced by her husband's name.

[1] Her essay, Försök att tillverka bröd, brännvin, stärkelse och puder af potater ('Attempts at Producing Bread, Spirit, Starch, and Powder from Potatoes') was also published by the Academy that year.

She was close friends with Queen Louisa Ulrika and held important positions in the royal court.
