TU-95採用後掠機翼，翼上裝4台渦輪發動機，每台發動機驅動兩個大直徑反轉四葉螺旋槳。這一安排相當獨特，同時也使TU-95成為最大、最快的螺旋槳大型飛機。機身細長，翼展和展弦比都很大，平尾和垂尾都有較大的後掠角。機翼為懸臂式中單翼形式，全金屬三梁結構，基本上由鋁合金製成。機翼內段1/4弦長後掠角37°，外段1/4弦長後掠角35°。展弦比8.4，相對厚度10～13%。外段機翼後緣有液壓操縱副翼，副翼上有調整片，副翼前有擾流片，有利於橫向操縱。機翼後緣內段裝有面積很大的後退式開縫襟翼，起飛時下放30°，升力係數1.67；著陸時下放45°，升力係數1.95。機翼上左右各裝3片翼刀。機翼前緣有熱空氣防冰裝置。
