Myrna Mack, Guatemalan anthropologist and activist (b. 1949)
Myrna Mack Chang (24 October 1949 – 11 September 1990) was a Guatemalan anthropologist. In 1990, she was assassinated by elements in the Guatemalan military due to her criticism of the Guatemala government's treatment of the indigenous Maya, and human rights abuses against the people in general.

Due to her sister's pursuit of justice, Mack's killer was convicted and upper-level superiors tried in precedent-setting cases before the Inter-American Court of Human Rights in Costa Rica. In 2004 the government of Guatemala acknowledged its responsibility and paid her family financial compensation.
