Szombathy is a Hungarian surname derived from the Hungarian word szombat meaning "Saturday". It belongs to a class of surnames originating from days of the week, often given to individuals born or baptized on that day, or to those who had some obligation or market-day connection to it. The suffix -y is a common Hungarian patronymic or place-name ending, indicating origin or association.
The surname is most prevalent in Hungary, with smaller populations in neighboring regions and the Hungarian diaspora. Like many Hungarian surnames, it may have been adopted during the 18th–19th centuries when family names became hereditary. Variant forms include Szombath or other dialectal spellings. While not common among historical nobility, it remains a recognizable marker of Hungarian linguistic heritage.
