Rancho San Geronimo was a 8,701-acre (35.21 km2) Mexican land grant in present-day Marin County, California given in 1844 by Governor Manuel Micheltorena to Rafael Cacho. The grant extended along San Geronimo Creek.

After decades of sale between landowners, the land was purchased by the Lagunitas Development Company who divided the rural land into Woodacre, San Geronimo, Forest Knolls, and Lagunitas, leading to its gradual suburbanization in the mid-20th century.

Despite its development, the Rancho "has managed to maintain its rural character, despite many threats of major development."
