Rio Bravo was a Mexican settlement established in 1849. It took its name from the Spanish name for the Kern River Rio Bravo de San Felipe.^[1]

Later Rio Bravo was called Panama, and after that name was applied to the current place, as Old Panama.^[1] The application of the name Panama was descriptive of the location as low, swampy, and plagued by mosquitos.^[1]
