The Tongva are indigenous to the Santa Monica area, where the village of Comicranga stood. Victoria Reid, daughter of its chief, was taken from her parents to Mission San Gabriel at the age of six. Gaspar de Portola's party, the first non-Native visitors, camped near today's Barrington and Ohio avenues on August 3, 1769. There are two accounts of the name. One says it honors the feast of St. Monica, mother of St. Augustine, though her feast falls on May 4. The other says Juan Crespi named the place for the Kuruvungna Springs, which reminded him of the tears St. Monica shed over her son.

In 1839 Governor Juan Bautista Alvarado granted Rancho San Vicente y Santa Monica to Francisco Sepulveda II. Its vague boundaries brought the Sepulvedas into conflict with the neighboring Rancho Boca de Santa Monica of Ysidro Reyes and Francisco Marquez, and a small Californio community of vaqueros and their families grew up on the rancho. American sovereignty began on February 2, 1848, under the Treaty of Guadalupe Hidalgo.
In the 1870s the Los Angeles and Independence Railroad linked Santa Monica with Los Angeles and with a wharf out into the bay. The first town hall, an 1873 brick building, later a beer hall, is now part of the Santa Monica Hostel, and by 1885 the town had its first hotel. In the early 20th century amusement piers and the Pacific Electric Railway brought crowds to the beaches, and a growing community of Asian Americans, including Japanese fishermen, lived in and around Santa Monica and Venice.
