Petaluma is a city in Sonoma County, California, United States, located in the North Bay region of the San Francisco Bay Area. Its population was 59,776 according to the 2020 census.
Petaluma's name comes from the Miwok village named Péta Lúuma that was located on the banks of the Petaluma River. The modern city originates in Rancho Petaluma, granted in 1834 to famed Californio statesman Mariano Guadalupe Vallejo, considered to be the founder of Petaluma. Today, Petaluma is known for its well-preserved historic center and as a local hub for the Petaluma Valley region of Sonoma County.

History
The Coast Miwok resided throughout Marin and southern Sonoma County. The village of Péta Lúuma (Coast Miwok for "backside of the hill", or "sloping ridge") was east of the Petaluma River, with a number of other Coast Miwok villages nearby: Wotoki was immediately to the south of Péta Lúuma, on the opposite side of the river; Etem, Likatiut, and Tuchayalin were near today's downtown; and Tulme and Susuli were just north of today's city limits.
The Petaluma area was part of a 66,000-acre (270 km2) 1834 Mexican land grant by Governor Jose Figueroa to Mariano Guadalupe Vallejo called Rancho Petaluma. In 1836, Vallejo ordered construction of his Rancho Petaluma Adobe, a ranch house near Petaluma, which his family often used as a summer home, while he resided in the neighboring town of Sonoma. Vallejo's influence and Mexican control in the region began to decline after Vallejo's arrest during the Bear Flag Revolt in 1846.
Pioneers moved to Petaluma from the eastern United States after James Marshall found gold in the Sierra Nevada in 1848. The town's position on the Petaluma River in the heart of productive farmland was critical to its growth during the 19th and early 20th centuries. Sailing scows, such as the scow schooner Alma (1892), and steamers plied the river between Petaluma and San Francisco, carrying agricultural produce and raw materials to the burgeoning city of San Francisco during the California Gold Rush.
There were brothels downtown along Petaluma Boulevard, which used to be the main thoroughfare until U.S. Highway 101 was constructed in the 1950s. The Petaluma Historic Commercial District is listed on the National Register of Historic Places.
The Sonoma County Bank Building was the home of the Baker Creek Heirloom Seed Company and the Petaluma Seed Bank until 2019. It was built in 1926.
Petaluma soon became known for its grain milling and chicken processing industries, which continue to the present day as a smaller fraction of its commerce. At one time, Petaluma was known as the "Egg Capital of the World," sparking such nicknames as "Chickaluma". Petaluma hosted the only known poultry drugstore and is the place where the coal lamp egg incubator was invented by Lyman Byce in 1879.
