Etymology and Origin

Kostelecký is a Czech surname that originally denoted a person from a village named Kostelec, derived from the Czech word kostel meaning "church". This pattern of toponymic surnames—named after a place of origin—is common in Czechia and other Slavic regions. The root place name Kostelec itself appears in multiple Czech localities, often indicating a site with a notable church, and shares a linguistic connection with words for church across many Slavic languages (e.g., Polish kościół).

The surname has been carried by several prominent individuals, particularly in the fields of sports and science. Alan Kostelecký is an American theoretical physicist of Czech heritage, known for his work in theoretical physics. In sports, David Kostelecký (born 1975) is a Czech sports shooter who won an Olympic gold medal, while Jaroslav Kostelecký (born 1979) is a Czech racing driver. The surname also appears in an anglicized spelling, Kostelecky, especially in the United States.
