Mercia MacDermott (née Adshead; Bulgarian: Мерсия Макдермот; 7 April 1927 – 28 March 2023) was an English writer and historian. She was known for her books on Bulgarian history.

Mercia was born on 7 April 1927 in Plymouth, Devon, United Kingdom.^[1] Her father was Geoffrey Palmer Adshead, a Royal Navy surgeon captain,^[2][3] and her mother was Olive May (née Orme) Adshead, a teacher. Due to her father's work in the navy, she spent some of her early years in Weihai, China, where Mercia learned Mandarin Chinese.^[4] She grew up in Ditchling and later was educated at Westonbirt School, Gloucestershire and St Anne's College, Oxford University where she read Russian Literature.^[5] In the summer of 1947, while participating in a youth brigade in Yugoslavia with other English students, she first met with Bulgarians, among whom was the poet Pavel Matev.

In 1948, she graduated with an MA degree from Oxford and visited Bulgaria to participate in the international youth brigade building the Koprinka Reservoir. As a foreign udarnik, Mercia was invited along with other international participants to meet Georgi Dimitrov in the Euxinograd palace on the Bulgarian Black Sea Coast. While working at the Koprinka reservoir, Mercia met her future husband James MacDermott. Returning to the United Kingdom in 1948, MacDermott enrolled in a Bulgarian language course at the University of London's School of Slavonic and East European Studies.^[6][7]

Mercia MacDermott visited and lived in Bulgaria from 1957 to 1989. From 1963 to 1964 and from 1973 to 1979 she was a teacher at the English Language High School in Sofia. MacDermott subsequently lectured on the Bulgarian national liberation movement in the region of Macedonia at Sofia University's Faculty of History.^[1] She was elected a foreign member of the Bulgarian Academy of Sciences in 1987.^[8] In 2007, Sofia University awarded her an Honorary Doctorate.
