Jose Rizal was born in 1861 to Francisco Mercado and Teodora Alonso in the town of Calamba in Laguna province. He had nine sisters and one brother. His parents were leaseholders of a hacienda and an accompanying rice farm by the Dominicans. Both their families had adopted the additional surnames of Rizal and Realonda in 1849, after Governor General Narciso Claveria

Jose Rizal's life is one of the most documented of 19th century Filipinos due to the vast and extensive records written by and about him. Almost everything in his short life is recorded somewhere, being himself a regular diarist and prolific letter writer, much of the material having survived. His biographers, however, have faced difficulty in translating his writings because of Rizal's habit of switching from one language to another.  They drew largely from his travel diaries with their insights of a young Asian encountering the West for the first time. They included his later trips, home and back again to Europe through Japan and the United States, and, finally, through his self-imposed exile in Hong Kong.  Shortly after he graduated from the Ateneo Municipal de Manila (now Ateneo de Manila University), Rizal (who was then 16 years old) and a friend, Mariano Katigbak, came to visit Rizal's maternal grandmother in Tondo, Manila. Mariano brought along his sister, Segunda Katigbak, a 14-year-old Batanguena from Lipa, Batangas. It was the first time they met and Rizal described Segunda as "rather short, with eyes that were eloquent and ardent at times and languid at others, rosy-cheeked, with an enchanting and provocative smile that revealed very beautiful teeth, and the air of a sylph; her entire self diffused a mysterious charm." His grandmother's guests were mostly college students and they knew that Rizal had skills in painting. They suggested that Rizal should make a portrait of Segunda. He complied reluctantly and made a pencil sketch of her. Unfortunately for him, Katigbak was engaged to Manuel Luz.  From December 1891 to June 1892, Rizal lived with his family in Number 2 of Rednaxela Terrace, Mid-levels, Hong Kong Island. Rizal used 5 D'Aguilar Street, Central district, Hong Kong Island, as his ophthalmologist clinic from 2 pm to 6 pm. This period of his life included his recorded affections of which nine were identified. They were Gertrude Beckett of Chalcot Crescent, London, wealthy and high-minded Nelly Boustead of the English and Iberian merchant family, last descendant of a noble Japanese family Seiko Usui (affectionately called O-Sei-san), his earlier friendship with Segunda Katigbak, Leonor Valenzuela, and eight-year romantic relationship with a distant cousin, Leonor Rivera (popularly thought to be the inspiration for the character of Maria Clara in Noli me tangere).
