Košice-Západ (literally: "Košice-West", Hungarian: Kassa-Nyugat) is a borough (city ward) of Košice, Slovakia. Located in the Košice II district, at an altitude of roughly above sea level, it is the most populous borough of the entire city. It borders the borough of Old Town in the east, Košice-Sever in the north, Sídlisko KVP in the west, Luník IX in the southwest and Košice-Juh in the southeast. The area of the borough is frequently nicknamed "Terasa".
Construction of the microdistrict began in the late 1950s and early 1960s, intended as one of the first major post-war developments in housing estate construction in Košice. The borough officially opened on the 22 February 1962. The working title for the development was Nové Mesto ("New Town"), reflecting its proximity to the nearby Old Town, but the more popular title adopted for the new borough became Terasa ("Terrace"). Currently, there are more than 39,000 people living in the borough, the highest population of all 22 boroughs of Košice.
The borough's housing estates built in the 1960s were dubbed "Luník", in honour of the Soviet Luna series of lunar probes. All of the Luník housing estates in Košice are located in the Košice-Západ borough (from Luník I to Luník VIII), the only exception being Luník IX, which forms its own borough.
