Healdsburg is a city located in Sonoma County, California, United States. At the 2020 census, the city had a population of 11,340.

Healdsburg is centered on a 19th-century plaza.

Early inhabitants of the local area included the Pomo people, who constructed villages in open areas along the Russian River. Anglo-American and Russian settlement may have commenced in the mid-19th century, with a settlement nearby, established downstream along the Russian River near Graton, in 1836, and later the Rancho Sotoyome land grant, in 1844.

In 1857, Harmon Heald, an Ohio businessman who had been squatting on Rancho Sotoyome since 1850, purchased part of the rancho—giving the city its official founding date. In 1867, Heald's eponymous small town was incorporated. Healdsburg is located within the former township of Mendocino. The San Francisco and North Pacific Railroad reached Healdsburg in 1872.

Farming, especially orchards and truck farms, was common within the present city limits from at least the 1890s to 1940s.

The first commercial development of the seasoning lemon pepper was in Healdsburg in 1967.

The city has a total area of 4.464 sq mi (11.6 km), of which 4.457 sq mi (11.5 km) is land and 0.007 sq mi (0.0 km) is water. The total area is 0.15% water. It lies on the Russian River, near a point used as a crossing of the river since the 1850s that is now the site of the Healdsburg Memorial Bridge.

Foss Creek traverses the city from north to south, flowing into Dry Creek near the U.S. 101 Central Healdsburg interchange.
