Meaning & origin
Estanislao is a rare Spanish form of the Polish name Stanisław, combining the Slavic roots for "stand" and "glory." Its U.S. usage is vanishingly small: the Social Security Administration recorded its first appearance in 1914, which also remains its peak year for usage. Since then, the name has appeared sporadically, never rising above a handful of births in any given year. As of 2025, the trajectory remains stable but exceedingly low, with no resurgence in sight. The name has no concentration in any specific U.S. state, reflecting its dispersed use among families with Polish or Spanish heritage. Estanislao offers a distinctive option for those drawn to saintly names with deep Slavic origins.
Derived from the Slavic elements "stani" (to stand, become) and "slav" (glory), making it a cognate of Stanisław. The name was introduced to Spain via the cult of Saint Estanislao Kostka, a 16th-century Polish Jesuit. Its Spanish form reflects adaptation to Iberian phonetics while retaining the original Slavic root.
