Zelezny

Zelezny is a surname of Czech origin, an Anglicized form of the Czech Železný, from the adjective železný meaning iron. Historically, it likely described a person who worked with iron or lived near ironworks. The name is most common in the Czech Republic and among people of Czech heritage, and in non-Czech contexts it is frequently written without diacritics as Zelezny.

Notable individuals with the surname include Jan Železný (born 1966), a Czech javelin thrower who is the world record holder with a mark of 98.48 meters set in 1996 and an Olympic gold medalist. The name is carried by other figures in sports, science, arts, and public life within Czech and Slovak communities; in English-language sources the form Zelezny is sometimes used.

In addition, the root Železný appears in several Czech place names and historic trades, reflecting a link to ironwork. However, Zelezny primarily functions as a personal name rather than a standalone geographic entity.
