Casa Navarro is a historic site in San Antonio, Bexar County, in the U.S. state of Texas. The original house complex was the residence of Texas patriot José Antonio Navarro (1795–1871), a rancher, merchant, leading advocate for Tejano rights, and one of only two native-born Texans to sign the Texas Declaration of Independence. Navarro first bought the property, about 1.5 acres, in 1832. The limestone, caliche block, and adobe structures were built c. 1832–1855, and Navarro moved onto the property soon after.
