Lina Marcela Medina de Jurado (Spanish pronunciation: [ˈlina meˈðina]; born 23 September 1933)[1] is a Peruvian woman who became the youngest confirmed mother in history when she gave birth to son Gerardo on 14 May 1939, aged five years, seven months, and 21 days.

The San Antonio Light newspaper in Texas reported in its 16 July 1939 edition that a Peruvian obstetrician and midwife association had demanded she be admitted to a national maternity hospital, and quoted reports in the Peruvian paper La Crónica that an American film studio had sent a representative "with authority to offer the sum of $5,000 to benefit the minor" in return for filming rights, but "we know that the offer was rejected".

[6] The article noted that Lozada had made films of Medina for scientific documentation and had shown them while addressing Peru's National Academy of Medicine.

Some of the films had fallen into a river on a visit to the girl's hometown, but enough remained to "intrigue the learned savants".

[1][10] According to Peruvian law, the mere fact of Medina's pregnancy meant that she had been raped at some point before her fifth birthday.

[1] Lina's father was arrested on suspicion of child sexual abuse but released due to lack of evidence.

[1] In young adulthood, Medina worked as a secretary in the Lima clinic of Lozada, which gave her an education and helped put her son through high school.
