巴西双鳍电鳐（学名：Narcine brasiliensis），又称巴西双鳍电鲼，为软骨鱼纲电鳐目双鳍电鳐科双鳍电鳐属的一种，分布于西大西洋区，从美国北卡罗莱纳州到[阿根廷]]北部, 包括墨西哥湾北部，小安地列斯群岛与犹加敦半岛海域，深度1至43米，本鱼头部、躯干和胸鳍连成一体，形成一厚且光滑之椭圆体盘，和尾鳍分开，两侧各具一纵走之皮褶，眼睛很小，喷水孔与眼有一定距离，后缘光滑，口小，唇厚，具强大之唇软骨。齿细小，背鳍2个，大小相同，位于尾鳍之上，体色白色，背面两侧有椭圆形的深色斑点，颜色从浅灰色到红褐色, 尾部有横向的深色条纹，有两个形状细长的电器官，从眼睛的前部一直延伸到圆盘的后端，体长可达54公分，栖息在沙泥底质海域，为夜行性底栖性鱼类，属肉食性，以多毛类、甲壳类、海葵、海星及硬骨鱼等为食，体内的发电器官，可能用来防御或捕食，卵胎生，会在11月和12月左右从北方迁移到深度约20米的区域，然后在5月和6月期间再次迁徙到深度约20米的区域。这种迁移主要是由于繁殖或进食所驱动，也与南方冬季的较高气温有关，据观察，如果它们在低于20 °C (68 °F)的水中，动作就会变得缓慢。
