デンキウナギ(電気鰻、英:Electric eels)は、デンキウナギ目ギュムノートゥス科[注 1]デンキウナギ属に分類される魚類の総称、もしくはそのうちの1種Electrophorus electricusの和名。南アメリカ大陸北部アマゾン川オリノコ川両水系に分布する大型魚で、熱帯淡水魚に分類される。最大860ボルトにもなる強力な電気を発生させて獲物を気絶させて狩りを行う強電気魚の1種として知られている。その電気魚としての形質は1775年に初めて研究対象となり、その後の1800年の電池の発明にも繋がった。本項では、デンキウナギ属(学名:Electrophorus)に分類される1属3種の魚類全般について扱う。
