Želénky (German: Schelenken) is a village, part of the village Zabrušany in the district of Teplice in the Ústí nad Labem region. It is located about one kilometer southwest of Zabrušany. The Ústí nad Labem - Chomutov railway line passes through here. The Bouřlivec stream flows through the village.

Želénky is also the name of a cadastral area with an area of 2,045 km².

Former porcelanite ("porcelain jasper") deposit in North Bohemian lignite basin. This buchite occurrence was caused by the fossil burning of a coal seam.

Apart from the listed minerals, Žáček et al. (2005) describe also Ca2SiO4, Ca7MgSi4O16 [= unrecognised bredigite?] and other unidentified Ca-, Mg- and Fe-bearing phases.
