Kostya is Russian, Slavic in Origin.

Kostya (Костя) is a Slavic hypocoristic of Konstantin, the Russian and East Slavic form of Constantine, from Latin Constantinus, ultimately derived from constans, meaning “steadfast, constant.” Used chiefly in Russian and Ukrainian, it is pronounced roughly KOSS-tya, with the palatalized -tya reflecting its familiar tone. While long rooted as a nickname within Orthodox Christian cultures where veneration of Constantine the Great popularized the base name, Kostya has occasionally been adopted as an independent given name in modern records and diasporic communities.

Literary visibility comes from Anton Chekhov’s The Seagull, where Konstantin Treplev is frequently addressed as Kostya, reinforcing its intimate, youthful register. Common variants and cognates include Konstantin (Rus./Ger.), Constantine (Eng.), Konstantinos and Kostas (Gr.), Constantino (It./Sp./Pt.), Kosta (South Slavic), Costin (Rom.), and Bulgarian Kostadin. Alternate diminutive spellings are Kostia and Kostja; further pet forms in Russian include Kostik. The core meaning across forms remains “steadfastness, reliability.”
