This paper provides an overview of the current knowledge concerning the longhorn beetles, inhabiting the Stobrawski Landscape Park, one of the largest protected areas of its kind in Poland. Drawing upon over 20 years of the authors' research and a comprehensive review of existing literature, a total of 92 species have been identified, representing nearly 47% of the indigenous longhorn beetles fauna. The research encompassed more than 50 distinct sites within the Park. Information regarding two species holds solely historical significance, as their presence has not been verified since the early 20th century – Oxymirus cursor L. and Monochamus sutor L.
