Klenik (pronounced [ˈkleːnik]) is a settlement east of Vače in the Municipality of Litija in central Slovenia.

It is now included with the rest of the municipality in the Central Sava Statistical Region; until January 2014 the municipality was part of the Central Slovenia Statistical Region.

[2] North of Klenik and east of Slemšek Hill (680 metres or 2,230 feet), near Vače, is the Hallstatt Archaeological Site in Vače, where the Vače situla, one of the most notable archaeological treasures of Slovenia, was discovered in the Ronkar Ravines (Slovene: Ronkarjeve drage, part of Klenik).

The local church, which stands on Slemšek Hill, is dedicated to the Holy Cross and belongs to the Parish of Vače.

The furnishings date from 1906 and were created by the Ljubljana sculptor Andrej Rovšek Jr.
