Kaštelir-Labinci ([needs Croatian IPA] Italian: Castellier-Santa Domenica) is a municipality in Istria, Croatia.

Kaštelir and Labinci have been gradually urbanized over the centuries, and have gradually merged into one place.

According to historical data, Labinci used to be a bigger place than Kaštela, but today Kašteliri is a bigger place, which is also evident from the name of the place.

[4] Throughout history, these two places were under the jurisdiction of Motovun and later Vižinada.
