مانعة الصواعق أو الشاري أو الحَرْبَة أو المِصْعَقَة هي عصىً معدنية متصلة بالأرض لها طرفان مدببان الأول يُثبتها على الأرض والآخر لجمع الشحنات وجذبها. تعمل مانعة الصواعق على امتصاص التيار الكهربائي الهائل الناتج من الصواعق وحماية الأجهزة والمعدات الكهربائية المركبة بالخطوط الهوائية من زيادة الجهد الناتج من العوامل الجوية. وقد اكتشفت من قبل العالم بنيامين فرانكلين.
