Koseze (pronounced [kɔˈseːzɛ]; German: Koßes[2]) is a formerly independent settlement in the northwest part of the capital Ljubljana in central Slovenia.

Koseze Pond in the village is a former clay pit[4] that supplied the brickworks operated by Gustav Tönnies (1814–1886) and was later flooded by the Agrostroj company to test irrigation pumps.

The name is originally an accusative plural demonym from the common noun *kosez, referring to lesser Slavic nobility.

[9] A bell tower was added to the church in 1708, and the building was badly damaged in the 1895 Ljubljana earthquake.

[13] The new church was designed by Anton Bitenc[4][12][14] with extensive stained glass by Stane Kregar (1905–1973).
