Zaj je Polje (German: Hasenfeld) is a settlement in the Ko evje municipality in southern Slovenia. It was inhabited mostly by Gottschee Germans. At the start of the Second World War its original population was expelled. The area is part of the traditional region of Lower Carniola and is now included in the Southeast Slovenia statistical region. The local church was originally a 17th century building dedicated to Saint Anthony, but it collapsed in 1741. In its place a chapel dedicated to Saint Valentine was built and this was converted to a church when a nave was added to it in 1867. It was demolished after the Second World War.
