Lukas Kladivko (Lukáš Kladívka) is a Czech artist working in graffiti, street art, installations, and mural painting. He initiated Woodoo Session, an international symposium focused on public-space art and street installations, and founded Mesto=Galerie in 2005, a Czech urban art festival dedicated to transforming public spaces through art.

In 2025, as part of the Mesto=Galerie project, he travelled to Ozurgeti, Georgia, to create a mural inspired by the city, its distinctive Georgian script, and the imaginative world of The Wizard of Oz.
