Lalla Fadhma n'Soumer or Lalla Fatma n'Soumer, Lalla Faḍma n Sumer in Kabyle (Berber: ⵍⴰⵍⵍⴰ ⴼⴰⴹⵎⴰ ⵏ ⵙⵓⵎⵎⵔ; born Fadhma Nat Sid Hmed; c.1830 – c. 1863) was an important figure of the Algerian resistance movement during the first years of the French colonial conquest of Algeria. She was seen as the embodiment of the struggle. Lalla, the female equivalent of sidi, is an honorific reserved for women of high rank, or who are venerated as saints. Fadhma is the Berber spelling of the Arabic name Fatima, which is colloquially pronounced Fatma in most Arabic dialects as well as Berber.
Her ashes were transferred in 1994 from the cemetery of Sidi Abdellah, 100 meters from the zawiya Boumâali in Tourtatine towards the Square of the Martyrs of El Alia Cemetery.
