The {{Nihongo|Tobu 7300 series|東武7300系|Tōbu 7300-kei}} was a DC electric multiple unit (EMU) commuter train type operated by the private railway operator Tobu Railway in Japan.

The 7300 series sets were built between September 1959 and 1964 from 58 former 63 series EMU cars purchased from both JNR and Meitetsu, with new bodies based on the 7800 series design.{{cite book| last = Iijima| first = Iwao | script-title=ja: 私鉄の車両２４ 東武鉄道 |trans-title=Private Railway Trains 24: Tobu Railway| publisher = Neko Publishing Co., Ltd. | date = July 2002 | location = Tokyo, Japan | page = 112| isbn = 978-4-87366-307-4| title = 東武鉄道 }} The last remaining sets were withdrawn by September 1984.
