Plačkovica is a mountain in the eastern part of Republic of Macedonia spanning the proximity of the cities Radoviš, Stip, and Vinica.
The highest peak is Lisec at 1754 m. This peak is a popular climbing route for the local climbers, being one of the harder peaks to climb in this part of Macedonia. It is not unusual to have snow on the peak during the month of June. The peak is served by two mountain lodges: "Vrteska" from Stip's side and, "Dzumaja" from Radoviš's side.
