Rancho Nueva Flandria was a Mexican land grant in present-day Yolo County, California given in 1844 by Governor Manuel Micheltorena to Jan Lows de Swart (John Schwartz). The name means "New Flanders" in honor of Swart's native country. The grant extended along the west bank of the Sacramento River, from present-day Bryte south to Merritt Island, and encompassed present-day West Sacramento. The land claim was rejected as fraudulent in 1857.
