Lista de condados en California

El estado estadounidense de California está dividido en 58 condados. El estado se dividió por primera vez en 27 condados el 18 de febrero de 1850. Estos se subdividieron aún más para formar dieciséis condados adicionales en 1860. Otros catorce condados se formaron a través de una subdivisión adicional de 1861 a 1893. El condado más reciente en formarse fue el condado de Imperial, en 1907.

California alberga el condado de San Bernardino, el condado más grande de los Estados Unidos contiguos, así como el condado de Los Ángeles, el condado más poblado de los Estados Unidos.

Los condados de California son condados de ley general por defecto, pero pueden ser autorizados según lo dispuesto en el Artículo XI, Sección 3 de la Constitución de California. A un condado chárter se le otorgan poderes limitados de autonomía. De los 58 condados de California, 14 se rigen por estatutos. Son Alameda, Butte, El Dorado, Fresno, Los Ángeles, Orange, Placer, Sacramento, San Bernardino, San Diego, San Francisco, San Mateo, Santa Clara y Tehama.

Nueve condados de California llevan nombres de santos, empatados con Luisiana por el mayor número. Este conteo omite el condado de Santa Cruz ("Santa Cruz") (no llamado así por un santo), el condado de Merced y el condado de Los Ángeles, cuyos nombres se refieren a Santa María, (es decir, Nuestra Señora de la Misericordia (Merced) y Our Lady Queen of The Angels (Los Ángeles)), y el condado de Ventura, cuyo nombre es una abreviatura del nombre de St. Bonaventure, el homónimo de la misión local.

Condados desaparecidos

• El condado Branciforte fue el nombre original del condado de Santa Cruz en 1850. La referencia fue a la ciudad de Branciforte de 1797.
• El condado de Klamath fue creado en 1851 desde la mitad norte del condado de Trinity. Parte del territorio del condado fue al Condado Del Norte en 1857, y en 1874 el resto se dividió entre los condados Humboldt y Siskiyou.
• El condado de Pautah, California fue creado en 1852 fuera del territorio que, según el estado de California, debía ser cedido a él por el Congreso de los Estados Unidos desde territorio en lo que ahora es el estado de Nevada. Cuando la cesión nunca ocurrió, la Legislatura Estatal de California abolió oficialmente el condado nunca organizado en 1859.
• El condado Buena Vista fue creado en 1855 por la Legislatura Estatal de California fuera del territorio sureste del condado de Tulare en el oeste de la Sierra Nevada pero nunca fue organizado oficialmente. El sur del condado de Tulare fue organizado posteriormente como el condado de Kern en 1866, con adiciones de los condados de Los Ángeles y San Bernardino.
• El condado de Coso fue creado en 1864 por la Legislatura Estatal de California fuera del territorio del condado de Mono y del condado de Tulare en la ladera este de la Sierra Nevada pero nunca fue organizado oficialmente. La región fue organizada posteriormente en 1866 como el Condado Inyo con adiciones de los condados de Los Ángeles y San Bernardino.
• Condado Roop, Nevada abarcaba gran parte del condado de Lassen, incluyendo el Valle del Lago de Miel y la comunidad de Susanville, California; la legislación orgánica ambigua de Territorio de Nevada llevó a confusión sobre la extensión geográfica de la frontera occidental de Nevada. Esto fue aclarado más tarde, con las porciones del condado de Roop en California que se asignan al condado de Lassen; las porciones restantes y escasamente del condado de Roop se combinaron con el condado de Washoe, Nevada.
