Let's Clean Slovenia 2012 (Slovene: Očistimo Slovenijo 2012) was a Slovenian environmental volunteer project organized by the environmental organization Ecologists Without Borders with the goal of joining 250,000 people on 24 March 2012 and cleaning municipal waste from illegal landfills in the country. Cleaning of scattered garbage in urban areas was also organized. The project, a continuation of the Let's Clean Slovenia in One Day! carried out two years before, was inspired by the Estonian campaign Let's Do It 2008 and organized within the frame of the World Cleanup 2012.
