In 1839, the Mexican government granted the Rancho Novato to Fernando Feliz. The rancho was named after a local Miwok leader who had probably been given the name of Saint Novatus at his baptism. Subsequently, four additional land grants were made in the area: Rancho Corte Madera de Novato, to John Martin in 1839; Rancho San Jose, to Ignacio Pacheco in 1840; Rancho Olompali, awarded in 1843 to Camilo Ynitia, son of a Coast Miwok chief; and Rancho Nicasio, by far the largest at , awarded to Pablo de la Guerra and John B.R. Cooper in 1844. Novato, along with the rest of California, became part of the United States on February 2, 1848. Early pioneers included Joseph Sweetser and Francis De Long who bought in the mid-1850s and planted orchards and vineyards.
