Karel Pečko (September 29, 1920 – May 2, 2016) was a Slovenian academic painter and cultural worker.

From 1954 to 1962, he taught art in primary and secondary school in Slovenj Gradec.

He also led the Slovenj Gradec Art Gallery (Slovene: Koroška galerija likovnih umetnosti) until 1997.

[1] He designed the exhibition programme and invited fine arts critics to participate as selectors, which was unusual in Slovene galleries in the 1960s.

Pečko wished to give Slovenj Gradec a cosmopolitan character with the help of the fine arts.
