Praviršulio tyrelis, also known as the Pravirsulio Tyrelis State Nature Reserve, is a nature reserve outside Šiauliai in Lithuania with many rare examples of flora and fauna. It officially became a botanical and zoological reserve in 1969 and has since become protected by the EU Habitats Directive and Birds Directive. At 3327 hectares the area is mostly a forest though around 13% of the land is a bog. The reserve is home to at least 100 different bird species, 14 of which appear in Lithuania's Red Book. ()
